I have just down loaded and installed v2.0.0 into C:Program Files. The installation appeared ok but now I can not import any step or stp files. I get some odd warnings about issues with fillets and others about the mesgher being busy. I have tried several files, some form the Models folder installed with the program. Stl files appear to import as expected. I have added an image of the error message
Program Files is admin protected folder. Move PrePoMax to a folder which is not admin protected and it will work.
thank you for your rapid reply -I was aware of the admin issues in that folder and had been running the program as an administrator. I have now re-installed direct to the c: folder but still get the same errors. I also tried installing version v2.0.0.3 and that gives me similar issues - unv and stl files still import ok

It seems the Netgen and its plugin for geometry import OCC is not working. Are you using a fresh Windows installation? Which version?
Thanks again for the reply - I’m using W11. Since u last mail I have read the instillation guide more carefully (perhpas I should have started there!!) and see "extract the .zip file to a non-system directory " I was not really sure exactly what that meant but coupled with ur advice in the ur first reply, I extracted the .zip file to my documents and now it is working just fine!. I have noticed, however, that on a few occasions where I have managed to crash prepomax, that when I restart it I can not import and .stp file and get the same errors reported earlier - the problem disappears when I restart windows - all a bit odd but not a big issue for me as it has not happened very often.
I must take this opportunity to say what a great program this is -I have not used it for some time but my interest got rekindled with some videos I saw about transfinite volume meshing. I am very impressed with the meshing capabilities of the program- a big step forward to what I have been using else where.

Thank you for the comments. We indeed have some problems with PrePoMax crushing occasionally, especially at the start of its use. But unfortunately, the problem is out of my hands to fix.
Good morning, I have the same problem with Windows 11. I installed prepomax in c: , but it doesn’t import the step files
that was the same for me - once I installed into “Documents” it all worked just fine -
hope u get it sorted
Thank you for your answer,
I tried installing in the “DOCUMENTS” folder and also in other folders… I also tried different versions (v2.0.0 v1.4.0 v1.3.2) but I always have the same problem:
… 02/08/24 15:33:47 The mesher is busy.
…02/08/24 15:33:47 at PrePoMax.Controller.ImportBrepPartFile(String brepFileName, Boolean showError)
…02/08/24 15:33:47 There were errors while importing the file/files.
…until a month ago I had no problems even with different versions.
Could it be a windows problem? or DLL?
It seems there are problems with versions where Gmsh was added. I will have to check this in a freshly installed Win 11 environment, but it will take me some time to prepare it. Hopefully, I can reproduce the problem.

After a bit of testing I think my “The mesher is busy” problem has been solved. I had to register the EXE file “NetGen\NetGenMesher.exe” in the DO NOT CHECK list in my antivirus (McAfee). After this operation the import of PrePoMax STEPs works perfectly.

I think this is a great find. I totally forgot about the anti-virus software. Thank you for posting the solution since it might be useful for other users.
