MSI installer not correctly uninstalling a product.
- by Ben
Hi,
I have a situation where a user can install an older version of my software for the 'current user', and then go ahead and upgrade to a newer version of my software for 'all users'.
The product itself works fine after this, but the strangeness happens on uninstall.
When I try to uninstall the product, the uninstaller shows a couple flashes of progress and then simply dies. It calls none of my custom actions at all (of which i have for install, uninstall, and commit. The product files remain, and I can still launch it.
If I try to uninstall again, MSI gives an error saying that the product doesn't exist, but it is still indeed listed on add/remove programs.
After this attempted uninstall, the user can work around the problem by uninstalling the 'rest' of the product through add/remove programs (which at this point shows the older version of the product).
Any Idea what could cause this?
