Thanks Blair, you're right, since I can't communicate with the package
author, I only have a choice to create a custom action that can modify
INSTALLDIR.
And I have the following:
----------------------------------------------------------------------------------------------------------------------------------------------------------
+++ My directory structure:
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="MYDIR" Name="My Directory"/>
</Directory>
+++ My custom action:
<CustomAction Id="SetMyMergeModulePath" Script="vbscript">
<![CDATA[
' code to modify Session.Property("INSTALLDIR") to its parent
]]>
</CustomAction>
+++
<InstallExecuteSequence>
<Custom Action="SetMyMergeModulePath" Before="CostInitialize" >NOT
Installed</Custom>
</InstallExecuteSequence>
----------------------------------------------------------------------------------------------------------------------------------------------------------
And it works with INSTALLDIR suplied from the command line installation
[msiexec ......INSTALLDIR ="...." ], which is good.
However it doesn't work if I enter INSTALLDIR from the UI.
The log show that MYDIR value is set right after INSTALLDIR is entered the
the UI dialog, even after that my custom action does actually modify
INSTALLDIR, its change does not help any more because MYDIR is already set
with the old INSTALLDIR.
I tried to modify MYDIR using another custom action, but modifying using
VBScripts through Session.Property("MYDIR") actually adds another MYDIR
property not the MYDIR of my merge module. Using custom action 35 to set
MYDIR after changing the INSTALLDIR like:
<CustomAction Id="SetMyDirPath"
Directory="MYDIR"
Value="[INSTALLDIR]\something " />
then it doesn't get [INSTALLDIR] (passed in empty)
I am so confused :)
Regards,
