I'm trying to get my upgrade/downgrade logic correct, and am having trouble
with FindRelatedProducts.
The output of my log looks like this:
Action start 17:35:33: FindRelatedProducts.
Action ended 17:35:33: FindRelatedProducts. Return value 1.
MSI (c) (9C:44) [17:35:33:309]: Skipping action: DemoOverwrites (condition
is false)
MSI (c) (9C:44) [17:35:33:309]: Skipping action: InstallingOldVersionError
(condition is false)
Now I can't really see why this would be the case, as I know that I have
installed a related product.
Here's the logic from my WiX Files:
<Upgrade Id='$(var.DemoUpgradeCode)'>
<UpgradeVersion OnlyDetect='yes' Property='NEWERDEMOFOUND'
ExcludeLanguages='yes' IncludeMinimum='no'
Minimum='$(var.DetectVersion)' />
<?if $(var.Demo)="1" ?>
<UpgradeVersion Property='OLDERDEMOFOUND'
ExcludeLanguages='yes' OnlyDetect='no' IncludeMaximum
='no' Maximum='$(var.DetectVersion)' />
<?else ?>
<!-- the next line is for release versions updating current versions
of the demo! -->
<UpgradeVersion Property='OLDERDEMOFOUND' OnlyDetect='no'
ExcludeLanguages='yes' IncludeMaximum ='yes'
Maximum='$(var.DetectVersion)' />
<?endif ?>
</Upgrade>
<Upgrade Id='$(var.RegisteredUpgradeCode)'>
<UpgradeVersion OnlyDetect='yes' Property='NEWERFULLVERSIONFOUND'
ExcludeLanguages='yes' IncludeMinimum='no'
Minimum='$(var.DetectVersion)' />
<UpgradeVersion OnlyDetect='no' Property='OLDERFULLVERSIONFOUND'
ExcludeLanguages='yes' IncludeMaximum='no'
Maximum='$(var.DetectVersion)' />
</Upgrade>
Any suggestions on how to debug this, as I'm getting nowhere. There doesn't
seem to be any reference to any of my properties in the log file, which I'm
generating with the msiexec -lvx option
