I had the same issue on Windows 10 when upgrading.  Rebooting didn't work, uninstalling etc..

 

I ended up searching for "Azure" in RegEdit and deleted two records similar to the ones in these screenshots. The Key name might be different for but if you search for Azure in that general area and find these delete them.  I just deleted the whole key and sub contents (MAKE BACKUPS FIRST, OR USE ON A NON-PRODUCTION TEST MACHINE) then tried to reinstall immediately worked, I'm now back to labeling files.

I had the same error,

my search was for: "Microsoft Azure Information Protection"

 

The registry keys i had to delete were:

[HKEY_CLASSES_ROOT\Installer\Products\81F60A84C159AC24681F0364FA601DE5]

[HKEY_CLASSES_ROOT\Installer\Products\993BF6477B270F046B2A7D4C218275F2]

 

Afterwards the installation was completed.

    Ofir Doron I made a one-liner to remove the keys which should make your life much easier. 

    for /f "tokens=1" %%a in ('reg.exe query "HKCR\Installer\Products" /f "Microsoft Azure Information Protection" /s  ^|findstr /ri "Installer"') do reg delete "%%a" /f

      Thanks Beancurd.

      It worked using single percent. Double percent will work running from a batch file.

        Running from command line:
        reg delete "HKEY_CLASSES_ROOT\Installer\Products\40258EB50B09D0744A45B91AE7C56045" /f
        and then re-installing worked. Thank you!
