Couldn't write Visual Studio Project assembly file C:\Users\...\AppData\Local\Microsoft\Dynamics Ax\VSAssemblies\Microsoft.Dynamics.ElsterTransferHandler.dll. Error code 32: The process cannot access the file because it is being used by another process.

I have installed three environment of Ax 2012 Featured Pack 6.0.947.862 in a client/server architecture.

Now I'm getting this error when I'm trying to open two reports, each one using differents AOS. One report in TEST environment and the other in DEV.

But this only occur a few times and then just stop.

I'm using the same account in both environment and for the BC.

What exactly should I do to fix this issue. Should I create another account for AOS and for BC or this is a bug?

Thanks.
