Resolve error code 191 "Installation or update failure" during Creative Cloud app installation or updates on Windows.
Note
If you encountered the error while installing Adobe XD, learn how to resolve error code 191.
Error code 191 generally occurs when you don't have the proper administrator privileges, your device doesn't meet technical requirements for installation, or your installation has failed to sideload a UWP package. To resolve the error, perform these solutions in order.
System login account may not have administrator privileges
If your system login account doesn't have administrator privileges, you may encounter error code 191. Follow these steps to resolve the error:
In the Run window, type netplwiz and select OK to open the User Accounts window.
In the Users tab, check if your system login account displays Administrators in the Group column. If Administrator is already selected, proceed to the next solution.
If you don't have administrator privileges, select your system login account and then select Properties.
In the Group Membership tab, select Administrator and choose Apply, and then select OK to confirm the changes.
Select OK in the User Accounts window.
Install or update the app again.
An existing build is installed on your device
While installing a Creative Cloud app, you might encounter "ERROR_DELETING_EXISTING_APPLICATIONDATA_STORE_FAILED" or a similar error. This happens when there is another Creative Cloud app package installed on your computer.
To resolve the error, delete the existing package and install the new package:
Type powershell in the Windows taskbar search.
Find Windows PowerShell, and right-click on it.
Select Run as Administrator, and then select Yes when prompted for consent.
Run the command: Add-AppxPackage -RegisterByFamilyName -MainPackage Adobe.CC.XD_{version}_x64__adky2gkssdxte to show (unhide) the existing package.
From the Apps & features list, locate and uninstall the Creative Cloud app.
Install the new package for your app from the Creative Cloud desktop app.
Certain folders on your device lack required permissions
Missing permissions for certain folders on your device can cause installation failure. To resolve the issue, provide read and write access to the required folders on your device:
Open File Explorer and enter the file path in the address bar:
- C:\Windows\temp
- C:\Users\<User Name>\AppData\Local\Temp
- C:\Users\<User Name>\AppData\Local\Packages
Right-click the root folder and select Properties > Security, and then select your system user account.
If a tick mark isn't visible under Allow for Read and Write, select Edit.
Check the box for Read and Write in the Allow column, and then select Apply to provide the required permissions.
Select OK to close the properties window.
After giving the required permissions to all three folders, install or update the app again.
Some components of Microsoft Store are damaged or corrupted
The error may occur due to corrupted components in Microsoft Store on your device. You can resolve the issue by resetting or reinstalling Microsoft Store:
Press Windows + R on your keyboard.
In the Run window, type WSReset.exe and select OK. An empty command prompt window opens along with Microsoft Store.
Wait for Microsoft Store to repair itself. The prompt automatically closes when Microsoft Store cache has been reset.
Once done, open Microsoft Store and install your app again.
If the issue persists, you may have to reinstall the Microsoft Store using Windows PowerShell.
Type PowerShell in the Windows search bar, and right-click Windows PowerShell in the search results.
Select Run as Administrator, and then select Yes when prompted for consent.
Run the command: Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}, and then press Enter.
Once done, open the Microsoft Store and install your Creative Cloud app again.
Operating system needs to be updated
