How to Fix “Another installation is in progress” Error on Windows

Our users reported that they could no longer install applications. Whenever they tried to install applications, they received the following message: “Another installation is in progress. You must complete that installation before continuing this one.”

The problem was due to a registry key-HKLM\SOFTWARE\Microsoft\CurrentVersion\Installer\InProgress.

As the name implies, the key is created when an installation is in progress. The key should be deleted automatically after the installation is done. In this case, the installation was never finished and the key was left in the registry. I tried to delete the registry key and rebooted the machine. It did not fix the problem. The registry key was created again after I rebooted the machine. I later found that the registry key was created by a program called ScreenConnect. I had to uninstall the program, but because of the registry key blocking installation and uninstallation, I could not uninstall ScreenConnect.

To solve this dilemma, I discovered that I needed to boot the machine to safe mode with networking, enable Windows installer service under safe mode with networking. Only then could I uninstall the program and fix the problem.

Here are the steps:

  1. Boot the computer to safe mode with networking. On a Windows 7 machine, you can do this by pressing F8 before the OS loads.
  2. Open an elevated command prompt.
  3. Type the following two commands in the command prompt. Note that the first command might be wrapped to the second line. Make sure you get it right.
    reg add "HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer" /VE /T REG_SZ /F /D "Service"
    net start msiserver
  4. Install a program. This could be any program using Windows installer. You will be prompted to cancel the previous pending installation. This is fine, so just follow the prompts to remove the pending installation.
  5. If you know which program caused the initial problem, you need to uninstall the program. In this case, our problem was caused by ScreenConnect, so I uninstalled it.

After you reboot the computer normally, you should be able to install applications without getting the “Another Installation is in Progress” error.

How to Configure Internet Explorer 10 for Enterprise Web Applications

Ever since we upgraded Internet Explorer to version 10, we have received a lot of complaints that quite a few enterprise web applications did not run properly any more. I have helped my users to configure Internet Explorer 10 so that they can use these web applications again. Since almost all the applications were developed before Internet Explorer 10, the first thing we tried to configure were the compatibility view settings. This would fix most of the problems. If this still did not work for some applications, the next thing to try was to configure the trusted site settings. Here are the steps. Remember to replace with the domain name of your enterprise applications.

Configuring Compatibility View Settings

  1. Press Alt key to bring up menu bar if it’s not showing.
  2. Click on Tools -> Compatibility View Settings.
  3. Enter in the “Add this website” box and click on Add.
  4. Click on Close.

Configuring Trusted Sites

  1. Press Alt key to bring up menu bar if it’s not showing.
  2. Click on Tools -> Internet options.
  3. Click on Security tab and select Trusted sites.
  4. Click on Sites.
  5. Enter * in the “Add this website to the zone” box and click on Add.
  6. Click on Close to close Trusted sites dialog.
  7. Click on OK to close Internet Options.


Windows 8 100% C Drive Usage Problem Solved

When I first upgraded my workstation to Windows 8, I did not notice any performance change. The machine was running as smoothly as it had been with Windows 7. However, a few weeks ago, I noticed my machine started to freeze intermittently. I checked the event logs but did not find anything out of the ordinary. I found out what went wrong when I checked the Task Manager. The CPU usage was fine, but Disk 1 (C:) was constantly at 100% usage and caused the machine to freeze. The question was what was causing the C drive usage to be at 100%? I then checked the Processes tab in Task Manager and found that it was the System process. This was not very useful because it was not specific enough for me to pin point the exact cause.

I googled for a solution and there were quite a few people who had the same problem. I tried several solutions but they did not help me solve my problem. This issue had bothered me for several weeks and I was about to reinstall my machine with Windows 7. I decided to give it another try, before I reformatted my drive (and then reinstalled my machine), and did a search again. Finally, I came across this post which solved the problem!

The problem was the Intel Rapid Storage driver. After I installed the latest version of the driver from Intel, the intermittent 100% C drive usage disappeared. Here is the link to the driver that I used:

Intel Rapid Storage Windows 8 Driver

The version I used is and it was released on 03/22/2013. If the link is broken, you can try visiting the Intel Download Center to search for the latest driver.

Intel Download Center

Note that this solution only applies to the Intel Rapid Storage controller. If you do not have the Intel Rapid Storage controller, do not download and install this driver.

To find out what storage controller you have, follow these steps:

  1. Press Windows key and type device manager.
  2. Click on Settings -> Device Manager.
  3. Scroll down and expand Storage controllers to find out what controller you have.

Once you have identified your storage controller, you can then try to visit the chipset manufacturer’s web site to download the latest driver and see if your problem is solved.

Lenovo X1 Carbon Unknown Device Driver on Windows 8

I worked on a Lenovo X1 Carbon yesterday. It’s a very capable machine. The CPU is an Intel Core i7-3667U. It comes with 8GB of DDR3L RAM and a Solid State Drive. The performance is amazingly fast. When I installed some software that would usually take half an hour to install on a recent computer, it only took 10 minutes on this machine. It’s even faster than my i7 workstation because of the solid state drive. The only downside to this machine is that the graphic card is an Intel HD 4000 that is not very powerful, but sufficient for business applications. The machine came with Windows 7 pre-installed. The user had requested Windows 8, so I first tried to do an upgrade installation. The compatibility report showed that there were a lot of drivers and applications incompatible with Windows 8. Therefore, I decided to do a clean installation. After installation, I installed Lenovo System Update. This is a utility to install all the necessary drivers and application for your Lenovo computers. You do not have to download each individual driver one by one. This saves you a lot of time. I wish the other vendors would follow suit and have such a utility. Anyway, after I installed all the drivers downloaded by System Update, I found that one device driver was not installed when I ran the Device Manager.  I usually use PCIDatabase web site to identify the device. It did not work in this case, because there is no vendor ID and device ID. Fortunately, it’s not difficult to find that info through Google. The search shows that it’s a iSCT ACPI Virtual Device (INT33A0) for Windows 8 (32-bit, 64-bit), Windows 7 (32-bit, 64-bit) – ThinkPad X1 Carbon After the driver was installed, there was no more unknown device in the Device Manager.

Movie Maker on Windows 8 Error: Movie Maker Can’t Start

I have used Windows Movie Maker on Windows 7 to make photo slideshows. It worked quite well. With a few clicks, you can produce professional quality slideshows that you can burn to DVDs. When I tried to run the program the first time, I got this error message:

Sorry, Movie Maker can’t start. Make sure your computer meets the minimum system requirements before trying to start Movie Maker again, and the try to update the driver for your video card if Move Maker still doesn’t start.


The message also provides two links for you to troubleshoot the problem. Before I checked the links, I remembered that the Movie Maker was installed before  the Windows 8 upgrade. I tried to download the latest version and install it. Unfortunately, it did not work, either. I received the same error message. I have used Movie Maker on this machine before, so I am pretty sure my computer meets the minimum requirement. I am also pretty sure that my video card driver is up to date because I just updated it a few days ago for Angry Birds. I tried the second link provided by the error message and found a solution to my problem. According to this post, I have to run Movie Maker in compatibility mode. If you are not sure how to do this, here are the step-by-step instructions.

  1. Press Windows key + E to run Windows Explorer.
  2. Navigate to this directory: C:\Program Files (x86)\Windows Live\Photo Gallery if you have 64 bit Windows 8. Otherwise, navigate to this directory. C:\Program Files\Windows Live\Photo Gallery
  3. Right click on MovieMaker.exe and select Properties.
  4. Click on Compatibility tab. Check the box “Run this program in compatibility mode for:” and select Windows 7.
  5. Click on OK to close the dialog.

You can now run Movie Maker. If this does not help, there is another post which might be helpful. Give it a try and let us know.

Angry Birds on Windows 8: OpenGL 1.4 Renderer Not Supported

I had trouble running Angry Birds on Windows 7 a few years ago. After my workstation was upgraded to Windows 8, I have not tried to install the game until today.

The game was installed using Intel AppUp. I first installed Intel AppUp and that went well. The installation of Angry Birds also went smoothly. However, an error message popped up when I tried to  run it.



This message was similar to the one I got when I ran it on Windows 7. The problem was due to the graphic card driver. I checked my current driver. The driver on Windows 8 was certified by Microsoft, but it did not work. If you checked Windows Update, there is no updated version of the driver. My graphic card is an AMD Radeon HD 4850. I then visited AMD’s website and downloaded the driver. After the successful installation of the updated graphic card driver, this problem was fixed. Here are the links to the major manufacturers of graphic cards.




Try to download and install the driver for your graphic card and see if the problem is fixed.


Cannot Enable On-Access Scanner for McAfee VirusScan

I recently helped a user with a McAfee VirusScan problem. The On-Access Scanner was turned off and when you tried to turn it on, it would not turn on. The user had just restarted the machine, so restarting the machine again was not an option. I tried to restart the services related to VirusScan, but the services were locked and I could not restart them. This is what I did to enable the On-Access Scanner.

  1. Open VirusScan Console.
  2. Click on Access Protection and click on Task -> Properties.
  3. Uncheck Prevent McAfee services from being stopped and click on OK. mcafee-access-protection
  4. Open up the services manager. You can do so by pressing Windows key + R, and type services.msc and enter.
  5. Stop the following services: McAfee Framework Service, McAfee McShield and McAfee Task Manager.
  6. Start the services mentioned in step 5.
