Cannot access AutoCAD Application interface

[Anonymous]

We installed some new antivirus software, and now the project manager doesn't function correctly. I can open existing drawgins, but I cannot add or create new drawings through the project manager. I get the following message from the Project Database Service: 'Cannot access AutoCAD Application interface'.

Any ideas on how to troubleshoot this?

A real quick question first off which will allow us to help you better...

What release of ACADE are you using?

Including this information in your questions will lead to quicker answers as each release of ACADE has some major differences from the prior releases.

To track down a problem or to answer a How-To question requires us to know which release we should be looking at and as much other information as possible (workflow which causes the problem as an example).

What AV software did you install?

Check the AV settings and see if it can be set to ignore ACAD.exe.

If all else fails, remove the new AV software and get something that will allow ACADE to run properly.
