Hi,
If you have installed Microsoft Office 2013 on your system then you are receiving below error dialog several times when opening and closing a DGN file.
I found below article but none of the steps mentioned, solved the problem.
After lots of search on the internet to be able solve the problem, we failed to find a solution. Then we uninstalled VBA using C:\BentleyDownloads\PreRequisite folder. Even VBA is not installed AECOSim still tries to load below VBAs and gives error messages.
How can I disable all VBAs that are loaded on startup? I failed to find any configuration variable that defines startup VBA macros. I also searched cfg files too.
