No. Windows says basically, oh, this is an MSI product so I'll just call the 
appropriate Msi API call directly.

Subject: [WiX-users] UninstallString is incorrect to uninstall the product.

This probably has to do with the fact that I have the element <MajorUpgrade> in 
the .wxs but I notice that in the registry the UninstallString is the same as 
the InstallString something like "msiexec -I{ABCDE....}". The software doesn't 
actually get uninstalled with this string I have to use (and the Add/Remove 
Program uses)  "msiexec -X{ABCDE....}" to uninstall the product. Is there a way 
to make the uninstall string something that will really uninstall the product?

Subject: [WiX-users] Detecting uninstall or minor upgrade


How do I detect uninstall or minor upgrade or first time install. I looked at 
the values in the table in the following article 
http://stackoverflow.com/questions/320921/how-to-add-a-wix-custom-action-that-happens-only-on-uninstall-via-msi
 and I don't think they are correct! Are they? Why do I need >(NOT 
UPGRADINGPRODUCTCODE) AND (REMOVE="ALL") to detect the uninstall if accoriding 
to the table NOT UPGRADINGPRODUCTCODE should be enough?
How do I easily check those values when the installer runs.
