Hi i'm an updater from v12.1 and had to uninstall v15 (manteinance updated) and run back to v12.1 cause with v15 it's impossible to create new custom layouts with all the driver in my pc (pdf24-microsoft-dwg2pdf). That's foundamental for my future works. Due to this issue the v15 i purchased is totally useless.
Please help me!

Please provide extra details on such matter.
pdf24-microsoft-dwg2pdf refers to a driver? Driver for what device?
What do you mean by not being able to create new custom layouts?

Yes. Those are the drivers i use to create custom layouts in CMS r12 Pro+ i own (more often DWG2PDF where i can select my custom layouts from a list).

Now in r15 after all configuring steps the list of Custom Paper Size is always empty.

I captured all the screenshots of the steps (11 screens) in a PDF and i would like to send you...but in this post can attach only images.

Is there a way to send you that PDF?

Thanks in advance
