Subject: Re: [WiX-users] Save and reuse previous InstallDir
OK. Let's make sure I'm doing part 2 right.
I'll deal with HKLM/HKCU issues, and part 1a (the app does not write to
the registry at all - this is an app that comes from the Unix world, so
I provided a default directory in past .msi's) once this is correct.
<!-- Assume the other boilerplate and stuff - I've written my own perl
program that generates a lot of it. -->
<!-- The next line will be replaced with a correct upgrade code.
Just assume it's correct. -->
<Upgrade Id='[% dist.msi_upgrade_code %]'>
<!-- two other upgrade entries here -->
<UpgradeVersion
Minimum='5.0.0'
IncludeMinimum='yes'
Maximum='5.12.0'
IncludeMaximum='no'
Language='1033'
Property='OLDERVERSIONBEINGUPGRADED' />
</Upgrade>
<Property Id="UpgradeDir">
<RegistrySearch Id="RS_InstallDir" Root="HKLM"
Key="Software\Microsoft\Windows\CurrentVersion\Uninstall\[OLDERVERSIONBEINGUPGRADED]"
Name="InstallLocation" Type="raw" />
</Property>
<Property Id='INSTALLDIR'>C:\strawberry\</Property>
<CustomAction Id="CA_GetARPInstallLoc" Property="INSTALLDIR"
Value="[UpgradeDir]" Execute="immediate"/>
<InstallUISequence>
<!-- QUESTION: Is this the correct point to do it? -->
<Custom Action="CA_GetARPInstallLoc" Before="CostInitialize">
OLDERVERSIONBEINGUPGRADED AND UpgradeDir
</Custom>
</InstallUISequence>
(I'm assuming that I have to do the CA somewhere in the middle of the
InstallUISequence.)
