Hi all,

my program uses the following registry value to get its location:
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\{PRODUCTCODE} -> InstallLocation (REG_SZ).

After a fresh install, it has the correct value.
After a patch (minor upgrade) is applied, this value becomes empty.

What should I do to make this persistent ?

I'm already writing the INSTALLDIR property somewhere else, but I thought everything under that key was taken care of automatically...?

Thank you,

Sophie

You should pick up the path in that value using AppSearch/RegLocator and store it in INSTALLDIR.

INSTALLDIR is fine, but why is the value cleared in the registry after a patch is applied ? That's what I don't understand...

[Stefan Krueger]

The patch is re-writing the registry entry (because a patch is a special form of reinstall). In this case the property is blank and therefore the registry entry is wiped out.

(I'm using IS X) found out that there was a condition on the SetARPINSTALLLOCATION CA. The condition was "Not Installed".

I removed the condition and the registry entry was kept after the patch/minor upgrade.

Thanks for your help

Sophie
