Installscript Custom Action and Mapped Drive
We have an Installscript custom action in our basic MSI install that does some configuration for our application. We were having UAC problems with it, so we changed it from Immediate Execution to Deferred Execution in System Context. We also had to move the custom action before the InstallFinalize action in the Execute sequence.
This all works fine when we install to a local drive, but when we install to a mapped drive on a remote system, the custom action never executes (we have SprintfMSiLog() calls that are not getting into the log). We ran with full MSI logging, and here is the section from the MSI log:
There is no indication of error, but our custom action code is not getting executed. Anyone have any ideas?

There is no indication of error, but our custom action code is not getting executed. Anyone have any ideas?

As I understand it, when the install elevates to admin privileges (as it does when items are run in System Context), the drive mappings for the user are not carried over. This due to the way UAC creates the admin security token, not to anything having to do with Windows Installer. I think you may have to use UNC paths in your custom action to get them to work.

Kathy,
Thanks, I think you found it. The first thing my custom action does is read the INSTALLDIR from the registry (since properties are not available) and then validate it. The validation would fail since the drive does not exist. This is done prior to outputting our log message. I will rework the code.

Hi Ibfahen,
Another point to be aware of, since it is relevant:
Q111936: INFO: Custom Action Fails when Copying a File from a UNC Path
http://kb.flexerasoftware.com/selfservice/viewContent.do?externalId=Q111936&sliceId=1
Basically "System Context" tries to access even a UNC path with a NULL user session, and will fail on any modern Windows OS. UNC complicates this since for proper elevation, you need the "System Context".
Kathey's point is also valid in this case, as Microsoft documents here:
http://support.microsoft.com/kb/937624
This also applies to open network share sessions, in case you authenticated with credentials other than what you logged on with.
