I keep getting this error every time we send and receive in a archicad teamwork project. It takes up allot of time.
" some libraries could not be received, because their local copies cannot be overwritten.

Note: This might be caused by multiple instances of Archicad using the same BIMcloud library.

Any help??

Hi eloise,

I suspect that you have two library parts stored under the very same name in one of your libraries.

Check your libraries and delete one or the other item - it should solve the issue.

Kind regards,

Hi Pawel,

Usually these elements are modification and duplication of an existing object in your library. If you modified any elements lately, it may worth to check these.

Also, if you you extract the affected library's container (, you can check duplicates with Windows File Explorer / macOS Finder too.

Unfortunately it's a manual work, there's no easier way in ARCHICAD.

Kind regards,

Hi. We get this error message from time to time. The error dialogue says another thing (not really sure what it actually says though... multiple instances of ArchiCAD using the same BS library...well that's the way Teamwork work...right!? The header in the error message says local library copies cannot be overwritten...and therefore recieve is blocked. Very confusing. I'm using the BIM-server libraries and don't bother about the theere a technical explanation from GS about what actually happens when receiving and sending...I'm notafter the Delta blah blah but a technical/practical explanation.
