[Bug 41269] MSI uninstaller does not clean up Registry's UpgradeCode, ProductCode

https://bugs.winehq.org/show_bug.cgi?id=41269

--- Comment #31 from Reinhold  ---
Thanks. This is a common issue like the one from Hans here in Comment 19 to 21.

In Hans' case the CustomAction has blocked installations from network drives
(where we often have issues therefore we have blocked that). In that case the
"Add/Remove" showed as if the app was properly installed. In order to proceed
with a next installation the "faulty" needs to be manually uninstalled with
"wine uninstaller".

We had many cases where customers were totally confused and we had fix that in
remote sessions jointly with customers. That is very service intensive.

May be it is a new bug. I am glad you got it.
