I have uninstalled and reinstalled VB, SQL, .NET Framework 2. I have
changed the project folder, and the publish folder and drive, there are
no errors in the event log, and to be honest I dont understand the
above output, what is missing that I dont have installed?
If it helps, the project uses the:
Imports Microsoft.Office.Core
Imports Microsoft.Office.Interop
Office is installed, as are all required assemblies, and it has worked
previously.
Hope this makes sense to you.
Please help
