I created a setup project with Wix Toolset, which does something like this:
* install (into ProgramFiles/MyApp, Desktop shortcut, StartMenu,...)
* create a folder ProgramFiles/MyApp/InstallFolder
* create some files in the folder ProgramFiles/MyApp/InstallFolder
* run a powershell script, which installs some COM+ components
In the ProgramFiles/MyApp/InstallFolder is also a powershell script, which
removes my COM+ applications (regsvcs /u). This script is executed as a custom
action on uninstall. But here I made a mistake - the custom action had the
attribute After="RemoveFiles" (it should of course be Before="RemoveFiles").
Now when I try to uninstall on my application, the uninstall process terminates
with the exception "There is a problem with this Windows installer package. A
program run as part of the setup did not finish as expected. Contact your
support personnel or package vendor.". The same exception occurs if I try to
install/repair/change my application...
Is there any possibility to uninstall my application without the last (faulty)
custom action? Or to 'overinstall' it somehow?
