i'm having problems wix customaction i'd run when user uninstalls application.

here's xml

the runtime.exe launches expected when installing application when uninstall error "the installer has encountered unexpected error installing package. may indicate problem package. error code 2753".

looking @ event viewer sheds little more light on problem, contains following "the installer has encountered unexpected error installing package. may indicate problem package. error code 2753. arguments are: file0, , ".

so, seems can't find runtime.exe i'm not sure why. file bundled msi , runs on install can't work out why doesn't run on uninstall.

many thanks

you should sequence uninstall custom action earlier. "before installfinalize" late, , results in attempting run program after removefiles has deleted it, hence error. @ installexecutesequence in msi file , see removefiles relative ca , installfinalize. may need before stopservices , other actions remove registry values, depending on how of installed product code needs. or run binary table (beware of dependencies) if needs literally before uninstall completes.
