You want:
Session.Property("PREVIOUS_PATH") = pathToProcess
But honestly, Script Custom Actions are very fragile. Consider C++ or C#
instead.

Subject: [WiX-users] Modify Public property from VBScript CustomAction
Hi everyone.
I try to modify public property from VBScript CustomAction but without any
success:
<CustomAction Id="ProcessPath" Script="vbscript">
<![CDATA[
pathToProcess = Session.Property("PREVIOUS_PATH")
pathToProcess = Replace(pathToProcess, "/", "\")
Session.SetProperty "PREVIOUS_PATH", pathToProcess
]]>
</CustomAction>
I tried Session["PREVIOUS_PATH"] = pathToProcess but it didn't work.
Is it possible to modify property values from script custom action?
The real problem is legacy application saves pathes with "/" slashes and
when installing new version Installer should copy files to directory with
those slahes (from registry) or default folder. But the path "C:/dir1/ is
interpreted as network location and with C:\dir1\ works perfectly.
<SetProperty Id="FilesPath" Value="[PREVIOUS_PATH]" After="CostInitialize"
>PREVIOUS_PATH</SetProperty>
FilePath is a Directory element. PREVIOUS_PATH is initialized with
RegistrySearch element.
Thank you!
