We encountered a problem: 
A Plugin returned one or more errors at the end of the transaction.
Additional error information:
The path to the MetaUninstaller executable could not be found on the system.




This may occur when the install is corrupted, and so the uninstaller files are not found in the file explorer on your PC.
