1721 error during uninstallation of a driver

10/27/2016 738 views

I have an card reader application which was repacked. I installed the driver creating a CA that executes dpinst.exe present in the package. 

Installation is happening fine and it's creating the entries under inf and Driverstore directories . 

I am handling the uninstallation team same way creating a CA . I am getting an error 1721 during uninstallation "There is problem with the windows installer package". CA is executed in differed mode after installfiles . 

It would be of great help , if someone could help me in this.

It could be any one of a 1,000 things. Your only option here is to use ProcMon to see where the package is failing.
