Thought i’d post this in case anyone else runs into this problem. I had worked through the issue with the help of an MSDN Post a while ago on one computer and while upgrading on another machine i ran into this error today and it took a while to remember the solution.
Heres the problem. If you have downloaded the latest GAX (for Feb 08 – v1.4.0.0), since you dont need to uninstall previous versions, you might race ahead and run the installer. Then you get a message saying
” A network error occurred while attempting to read from the file:C:\TEMP\[GuidanceAutomationExtensions - Feb 2007.msi]“.
This occurs because the new MSI is working in upgrade mode and is looking for the old one. The MSI name in the errror message is the same name as whatever you called the MSI when you installed it. (For some it might be just guidanceAutomationExtensions.msi but I keep all the MSIs for GAT/GAX in one folder so i need to rename the default download to suffix the release name- The error message indicates sucha a renamed MSI).
The solution: If you have the GAX exe download, simply unzip the contents to a folder and then place the old MSI alongside this. (If you dont have the old MSI, it maybe possible to re-download the old version and then name it the same as the file name that appeared in the error message (forget the C:\TEMP\ bit, thats not necessary). Now run the setup again and it works fine.
With GAT, you can just uninstall the old version and run the new install and it works fine.
Hope this helps if you have this issue.
Thanks a lot !!! A great tip.
