I think you are correct......I'm trying to find where %srcdrv% is set (it's been a few months since I put this together).

When I install from media %srcdrv% is probably the cd drive or jump drive.....but when I download from the web.....it is being loaded from a download directory on C & %srcdrv% is probably not set.

Not sure how to show %srcdrv% in the message box....

Will I need a different installer to install from the web and use something like %tmpdir% instead of %srcdrv%
