I've been on this for a few hours now. I'm trying to write an upgrade. From
what I understand, it should be as simple as adding a MajorUpgrade section with
a DowngradeErrorMessage string, and having the same upgrade code. However, it
just isn't working out that way. I can install the old product with the same
name and same upgrade code, then install the new product, and it just ignores
the old one. I've dug through the WindowsInstaller log, and nothing jumps out
at me. It doesn't say anything about detecting the previous version. It does
run RemoveExistingProducts:MSI (s) (00:C4) [20:25:10:060]: Doing action:

RemoveExistingProducts. Return value 1.
One hint is that the ProductVersion property of the old product is incorrectly
formed. The person that did it wanted to use a date for the build number, so
here is the old version number: "2.0005.043012".
Could this be why upgrade isn't working? I'm using "2.49.1" for the new
version. Still, if it doesn't detect the old one as being older, it should
give me an error, not just ignore the old one, right?
This is my first post here, so please let me know if I've violated any
etiquette rules. :-)
