Ryan,
You did not show all the relevant to major upgrade code:
- Did you change the Product/@Id, Package/@Id, and Product/@Version?
- Do you have Product/@Language listed in or equal to
Package/@Languages?
- Do you schedule a RemoveExistingProducts action in the
InstallExecutesequence?
- Do you use custom action to prevent downgrading?
Regard,
Alex

Subject: [WiX-users] Unable to force upgrade
In my attempts to force an application to uninstall completely before being
reinstalled (major upgrade) I have followed the instructions here
(http://www.tramontana.co.hu/wix/lesson4.php) and I keep getting 'another
version of this product is already installed'. I've kind of inherited this
installer so I am still learning about what it does, is it possible that the
upgrade is being stopped by a custom action or is the fault in the code below?
I've also checked
http://blogs.technet.com/alexshev/archive/2008/02/15/from-msi-to-wix-part-8-major-upgrade.aspx
but can't see what I am missing.
Any help would be much appreciated.
<?define FirstProductVersion="0.8.0" ?>
<?define ProductVersion="0.9.0" ?>

</Upgrade>
