Basically, you can't just run the MSI for small/minor upgrades-you have
to pass in the command line msiexec /i install.msi REINSTALL=ALL
REINSTALLMODE=vomus . Not sure why-can anyone here shed some light on
the subject?

Subject: [WiX-users] Another version of this product is already
installed
I'm trying to come to grips with how upgrades are handled, and I was
wondering if someone could shed some light on the subject for me.
In an attempt to understand better, I've been trying to install a pseudo
"minor upgrade".
I installed the base version, then I tried to install the slightly
modified "upgrade" version.
I changed:
Product Version attribute.
Package Id (auto generated)
The contents of one text file.
I left unchanged:
Everything else, including Product Id & UpgradeCode
Each time I've tried, I get the "Another version of this product is
already installed" dialog.
What gives?
