Im trying to create MST for the vendor MSI of Cicso IP COmmunicator.Im able to install and uninstall.But when im again trying to Install after uninstallation, It gives error saying "cpmtdriverinstall.exe" is not able to complete the process it should do and the installation fails.
I guess the uninstall is not clean enough...cpmt driver is a kernel driver. When trying to install after uninstallation its trying to update the driver and fails at that point as per the log.

Can anyone please help me at this point.

Thank u in advance..[:)]

I'd do a repackaging snapshot, insall the MSI, uninstall the MSI, then do a final snapshot. That should tell you what noise is being left behind. Then create a custom action in your MST that cleans up the noise on remove only.

There is no documented way to Uninstall Device Drivers!

This is a MS problem and the only solution offered is a program called DEVCON. This will remove drivers but has its flaws and can also render PNP registry keys as unusable.

My recommendation is to not try to uninstall drivers but leave them there and if the hardware is unplugged they are dormant anyway and do not pose any issue to the OS.

With Cisco IP Communicator you need a reboot to clear the driver uninstall if you use the Cisco msi file. Kernal service layer services and drivers require a reboot because they are processed at boot time and not at login.

Create a reboot msi package and install that as part of your upgrade so that the PC reboots before the install of the new version
