Thank you Shawn.

In this case, is any newer Personal Isogen that is functional with Caesar? For the time being I can not use it as you can see.

Just as a comment, while it must be true that the files should not be mixed, at least the idfgen.dll from 5.1 seems until now to solve the 45 deg bends issue in 5.3.

What can be done?

Regards,
