How to Fix Sage Cannot Open Activation Key File Error
Here are some simple methods to resolve this error –
Total Time: 30 minutes
Check if you have Insufficient Permissions
🔹 Open the Windows explorer
🔹 Browse to “..\MAS90\Home\Lib\Keys“.
🔹 Try creating and deleting a text file in this folder.
🔹 If you are getting an access error, it means you do not have the sufficient privilege
🔹 To have sufficient rights, Right click on the Sage shortcut on your desktop and choose Run As Administrator
🔹 Open Windows explorer
🔹 Browse to the “..\MAS90 folder
🔹 Change the permission for this folder to ‘Full Control’ at the Sharepoint
If the activate.pvx File is Corrupt or Missing
🔹 Log in to the server with admin rights
🔹 Open Windows explorer
🔹 Browse to the “..\MAS90\Home\Lib\Keys” folder
🔹 If you can locate the activate.pvx file in this folder, try to replace it with a backup copy
🔹 If you find it renamed (such as MIGRATE_ACTIVATE.PVX), try renaming it back to activate.pvx
🔹 Try to open the Sage software and check if you are still getting the error
🔹 If the error still persists, the activate.pvx is read-only. This may occur if you have restored the Sage backup from a CD-ROM. In this case, you will need to remove the “Read-Only” attributes from all Sage files
🔹 Open the command prompt
🔹 Browse to the “..\MAS90” folder
🔹 Type the ATTRIB -r -s -h /s command to remove the “Read-Only”, “Hidden” and “System” attributes from the ..\MAS90 folder and all its subfolders
If the Path to “..\MAS90” is Incorrectly Mapped
🔹 Log in to the server
🔹 Remove the share from the “..\MAS90” directory
🔹 Now share the drive above ..\MAS90\.
🔹 Go to the workstation and map the drive again to point it to the new share point,
🔹 Run the Workstation Setup (Wksetup.exe or..\MAS90\Wksetup\Setup.exe).
If the Sage Program is Infected by a Virus
🔹 Rename the “..\MAS90\CM” and “..\MAS90\Home” directories.
🔹 Reinstall the System Setup module
🔹 Also reinstall the Library Master and Custom Office modules, if installed
🔹 Go to Product Registration and Reactivate the system. You are not required to reenter the unlocking keys and serial numbers.
🔹 To retain the configuration settings, copy all the *.ini files from the original “..\MAS90\Home” directory to the newly created “..\MAS90\Home” directory.
