karenz 0 Report post Posted June 13, 2015 This morning I tried to restore my TMG project on my second computer, and when I clicked on Restore from the Welcome screen I got this: Please wait while Windows configures AutoCad (went by too quickly to capture, but it said something like that) Then: AutoCAD LT 2015 The feature you are trying to use is on a network resource that is unavailable. Click OK to try again, or enter an alternate path to a folder containing the installation package 'acadt.msi' in the box below. Use source: c:\Users\ etc. I clicked out of that, and could enter TMG in Repair Mode. I ran all the maintenance procedures, and backed-up and exited. Then I made a second attempt to open TMG and got the same AutoCad messages. I clicked on cancel and got this: Error 1706. No valid source could be found for the product AutoCad LT 2015 - English. The Windows installer cannot continue. clicked OK. TMG started normally at this point. Any ideas why opening TMG is trying to install AutoCad? - which by the way has been installed for a while and running normally. What can I do to avoid this problem in the future?
