Hi Charles,

From your description, you have a VS built setup package which has some
problem with a custom action component which always cause the setup to
rollback during uninstall time, correct?

As for the "bug", do you mean a known issue from the microsoft site or a
potential problem in your code? If the problem is mainly specific to the
custom action class, would you provide some further info on it? What code
have you used in your custom action class(especially in the uninstall
method), if possible, it would be helpful if we can create a simplified
version to repro the exact same problem.

here is a tool for custom action debugging:

Please feel free to let me know if there is anything I missed.

Sincerely,
