Answer:
Generally, any changes to the COM Interface are listed in our update report for the respective module. All update reports are available in the Dlubal extranet.
If there is a modification of the COM Interface, it is listed there. Especially when converting the older COM interfaces from RSTAB6/RFEM3 to RSTAB8/RFEM5, complete compatibility is not guaranteed due to the change from tlbs in the VBA to an integrated solution with dlls.
However, it is usually possible to overwrite dlls within the current COM interface without any problems. For additional security, we always recommend backing up the old files.
