We distribute an add-in to our clients. I have had a client who has not been able to load our Add-In. After failing to diagnosis the issue I asked him to try to load the Solver-AddIn and he is getting the same error message (just the filename/path is different)
Microsoft Excel cannot access the file'C:\Program Files\Microsoft Office\Office12\Library\SOLVER\SOLVER.XLAM'.
There are several possible reasons:
The file name or path does not exist.
The file is being used by another program.
The workbook you are trying to save has the same name as a currently open workbook.
I have Googled for this and the only thing I can find suggests we contact MS Technical Support. We are about ready to do that but I wanted to check to see if someone else has had this problem.
I want to note that we tried moving the AddIns to different locations but get the same error message varying only in the path to the AddIn.
