Question

I have created a Custom Action named UninstallDokan,which Dokan is driver for my software.I encounter the errorwhen I uninstall my program:
Error 1721:
There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor. Action:UnistallDockan,location:,command:C:\program Files <86>\DoTask\Driver\DokanUninstall.exe
The CA is configured as follows:

Created a CA based on "New EXE > Path referencing a directory".
Working Directory: <empty>
Filename & Command line: "[INSTALLDIR]\Driver\Uninstall.exe"
Return Processing: Synchronous (Check exit code)
In-Script Execution: Commit Execution in System Context
Install Exec Sequence: After RemoveFile
Install Exec Condition: Remove
everything else was left at the default

Do anyone have any ideas what to try next?
