Workaround to fix Office Preview app error “This app can’t open”

Office Preview app or several other modern apps, either didn’t open or displayed an error “This app can’t open, Check the Windows Store for more info” when launched on Windows 10 TP. Microsoft has identified the cause and provided workaround with script to purges all licenses cached on device and allow refresh of all valid licenses because the issue was related to Store Licensing Service.

Store Licensing Service fails to acquire a new license if one already existed, even if the license had expired. Removing and reinstalling doesn’t clear the cache so the app fails to get the license at startup. If you had installed the app prior to Feb. 23 then you would hit this issue and removing and reinstalling the app won’t fix the problem.

Step-by-step Instructions:

1. Open Notepad and paste below text

echo off
net stop clipsvc
if "%1"=="" (
echo ==== BACKING UP LOCAL LICENSES
move %windir%serviceprofileslocalserviceappdatalocalmicrosoftclipsvctokens.dat %windir%serviceprofileslocalserviceappdatalocalmicrosoftclipsvctokens.bak
)
if "%1"=="recover" (
echo ==== RECOVERING LICENSES FROM BACKUP
copy %windir%serviceprofileslocalserviceappdatalocalmicrosoftclipsvctokens.bak %windir%serviceprofileslocalserviceappdatalocalmicrosoftclipsvctokens.dat
)
net start clipsvc

2. Save the file with some name as “activelic.bat” (note the .bat extension)

3. Right click Start button (window logo), open ‘Command Prompt (Admin)’. Execute the batch file from this admin command prompt.

4. Go to Start menu and uninstall the App exhibiting the behavior.

5. Reacquire the App. Launch it and it should now open, reacquire a new, valid, license.

Script is actually stopping client license service, renaming the cache and restarting it again. The cache will update as apps are launched.
