mine known person also received same letter about using cracked version of solidworks 2022, but he ignored everything as i said him from info on this forum (emails from 3ds.com and cjch), 1 year already, nothing more... they wanted 23k EUR for this usage... before he was using version 2015, there was no any problem (no any anti piracy mechanism inside) I think they enabled some hidden mechanism inside software to report non licensed usage (license server emulator), but it will not send info from first start of using, this mechanism somehow calculate hours used in program and only then send info to 3ds, because dates of usage which he received in letter was 1-2 weeks later of starting usage... Also per searching info how they got email we discovered that they sniff traffic or scan local outlook/email apps to find contacts, because my known person received email to company email, but there was no info anywhere about where he is using it, he also has dynamic ip which changes time to time, etc. ----------------------- Following your receipt of a letter sent by CJCH solicitors (Dassault Systems’ legal representative) on xxx,xxx 2022 to outline a case for unauthorized download of SOLIDWORKS within your company, I have been assigned to engage with you and consider how we can resolve this matter together and without the need for further legal involvement.
