We recently moved the server the Revit Templates and libraries were stored on. I was able to update Revit settings, updating the Revit.ini to reconfigure the correct locations. All paths are correct within Revit, and I also checked the registry keys for Revit to make sure everything was pointed in the right place.
However if I try to update Revit (eg Update3) or uninstall Revit, I get the following error from MS Installer
Error 1606. Could not access network location \\oldserver\autodesk\revit\Revit Library Components\
Then
A problem prevented the Update Release from being installed. Contact your system administrator. Error Code 1603
Can anyone help?
