The problems came back again, but it seems I was able to figure it out 🙁

I found the log file at: c:\ProgramData\Microsoft\Windows\WER\ReportArchive\

There are 21 folders with Poser errors (NonCritical_Poser.exe) and in each folder there is a file (Report.wer) with the following wording:

EventType=FaultTolerantHeap

I tried to look for what this means, some users had the same problems for quite a long time with iClone 6.4 or some other 3d programs, and just renaming the folder helped them. I tried to do the same, for example, the folder was called Poser 13, I renamed it Poser 13 1 and the problems disappeared! At least 2 days without problems.

So if anyone has similar problems, then just try to rename the main folder with the program. Because of this, no other errors occurred, all paths to the libraries remained working!
