We have a product (ver. 1.0) installer that creates Windows registry values under the key HKEY_LOCAL_MACHINE\SOFTWARE\MyCompany\MyProduct\1.0. We have a servicepack installer (ver. 1.0.1) that updates files in the existing 1.0 installation.
When I run our uninstaller, which is supposed to remove everything, not just the recent SP, it leaves behind the registry key HKLM\...\1.0 and its values and I get the following error on the final panel:
Unable to remove registry key: HKEY_LOCAL_MACHINE\SOFTWARE\MyCompany|983359||STRING|
After the original 1.0 install, the uninstall registry .com.zerog.registry.xml has lines similar to this:
And after installing our SP, those lines are missing. Has anyone seen this before?
The issue for us was some install actions were somehow not assigned to a component so they were not recorded for uninstall. In your Install Actions view, make sure the "Assign to" dropdown is set to Components and make sure all actions are assigned to a component.
