Many a time Windows 10 Update get stuck. The update downloads just fine, but when the system goes ahead to update further, an error like incompatible applications, blocking applications, and the Error code Oxc1900208 shows up. All this keep happening because few applications block the update process. What do you do when Windows 10 Setup throws you a message – Uninstall this app now because it isn’t compatible with Windows 10? It may be acompanied by Error Code 0xc1900208. If it is installed, you may select the Manually uninstall option. But sometimes the applications are not even installed, but they have traces in form of associations. This process lets you identify & remove those associations.
In this post, we will talk about how to remove blocking applications which don’t allow Windows 10 Update to complete.
Uninstall this app now because it isn’t compatible with Windows 10
Steps to remove blocking applications
The reason Windows 10 Upgrade fails, is because of apps that are not compatible with the next version of Windows. Chances are that they would work, but they haven’t passed through the compatibility check. When you run Windows 10 Upgrade Advisor, the system checks for such apps and warns you. The same happens during every upgrade.
While it usually should not block, but things don’t go straight all the time. Many a time it may so happen that the app is not installed on your PC, but it is likely that the compatibility checker is detecting a file associated with the app, rather than the app itself.
You will need to delete the file it is detecting before you can install the upgrade. You can determine which file is triggering the block by examining a hidden log file.
To do this, follow these steps:
- Open File Explorer and click the View tab. Make sure to select the checkbox for Hidden items.
- Select This PC, and type *_APPRAISER_HumanReadable.xml in the search box and search the PC for file names that end with this term.
- Right-click the file that ends with _APPRAISER_HumanReadable.xml and opens the file with Notepad.
- Press CTRL + F and search for DT_ANY_FMC_BlockingApplication. Look for the value, it should be True.
- Press CTRL + F and search for LowerCaseLongPathUnexpanded. The value contains the file path of the program. You should remove or transfer to another drive. (It should be located approximately 28 lines under the DT_ANY_FMC_BlockingApplication).
- Make note of the file path listed in the value for LowerCaseLongPathUnexpanded. You can select the file path and copy it to the Notepad by pressing CTRL + C.
- Navigate to the file path’s location in File Explorer. (Click on File Explorer’s address bar and press CTRL + V to paste the file path you copied earlier.)
- Once you’ve located the blocking.exe file, transfer the file to another drive or Delete the file.
PowerShell Script to fix remove blocking applications
If you find the above step difficult, you can download this PowerScript file from Microsoft, and run it when you face this blocking applications error. A zip file with name AppRPS.zip will download on your computer.
Once you had unzipped the script file, run it with Administrator privilege. Once the blocking file is moved or deleted, try installing the Windows 10 upgrade again, or return to the Windows 10 Upgrade Assistant and select the Refresh button.
Hope this helps!
