Incompatible applications

Hello Linda,

Before you can upgrade to the latest version of Windows, Setup performs a compatibility check to make sure you don’t have any apps installed that are known to be incompatible with that version of Windows.

If you are blocked by an app you don’t appear to have installed, 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:

1. Open File explorer and click the View tab. Make sure the check box for Hidden items is selected.
2. Select This PC, and type *_APPRAISER_HumanReadable.xml in the search box and search the PC for file names that end with this term.  
3. Right click the file that ends with _APPRAISER_HumanReadable.xml and open the file with Notepad.
4. Press CTRL + F and search for DT_ANY_FMC_BlockingApplication. Look for the value, it should be True.
5. Press CTRL + F and search for LowerCaseLongPathUnexpanded. The value contains the file path of the program that should be removed or transferred to another drive.  (It should be located approximately 28 lines under the DT_ANY_FMC_BlockingApplication).
6. 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.
7. Navigate to the file path’s location in File Explorer.  (Click in File Explorer’s address bar and press CTRL + V to paste the file path you copied earlier.)
8. Once you’ve located the blocking.exe file, transfer the file to another drive or Delete the file.

You may also download run this batch file to automatically perform the steps above: https://aka.ms/AppRPS (You should be prompted to download a zip file named AppRPS.zip)

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.
