Sorry about reposting this; I put it in the wrong forum initially...
My installer allows the user to specify the folder location for the initial
install. But on an upgrade, I'd like to prevent them from changing that
location, so I don't allow them to specify the folder.
I think I understand how to get the folder name of the original location on
upgrade: My code uses "*" for product code, so a new one is generated with
each build. I have a Custom Action in a DLL which will use
MsiGetComponentPath with the value of "OLDERVERSIONBEINGUPGRADED" to
determine the folder. I think that this property contains the ProductCode
of the version being upgraded. OLDERVERSIONBEINGUPGRADED is set by this
code:
<Upgrade Id="$(var.UpgradeCode)">
<UpgradeVersion Minimum="$(var.ProductVersion)" OnlyDetect="yes"
Property="NEWERVERSIONDETECTED" />
<UpgradeVersion Minimum="0.0.0" Maximum="$(var.ProductVersion)"
IncludeMinimum="yes" IncludeMaximum="no"
Property="OLDERVERSIONBEINGUPGRADED" />
</Upgrade>
Right now, I am setting the INSTALLDIR to a hard-coded value, like this:
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="foo" Name="MyCompany Name">
<Directory Id="INSTALLDIR" Name="My Product Name">
</Directory>
</Directory>
</Directory>
... rest of installable components ...
</Directory>
My question is, how do I set INSTALLDIR to the value returned by the call to
MsiGetComponentPath, and when should it be scheduled?
Thanks
