Getting an error for the gmsh trying the extrusion example, any ideas ? ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/8/85369f109f0645911897d17f35eb913194ad77dc.png) ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/1/184fa53c4018b94b8e1bb6662412f1aeb6536ffc.png) ---

The first screenshot is from 2.0.0 but the second one shows files from 2.0.2. Is this GmshCommon.dll file also present in the folder with 2.0.0 ? ---

Yes, I tried both versions. Dll is present in both. ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/3/364071a1913f31f6cad403d8339db07e71993860.png) Is anyone else using windows 11 ? Just seems strange I’m having issues with dll’s, this and the use of ccx\_dynamic. ---

I had a different GMSH error a while ago. I then moved the PrePoMax installation folder to my computer root, such as C:/PrePoMax. Maybe this can help. ---

Yes, I saw that post, I did try but made no difference. ---

Did you try any other Gmsh features? Can you try downloading and running the native Gmsh to see if it works? ---

I downloaded Gmsh and that is functional. I can’t get any Gmsh functions to run in prepomax, all give the same error. Ill try on another device. ---

Did you try different versions of PrePoMax that support Gmsh? ---

I tried 2.0.0 and 2.0.2 dev I’m running Windows 11 pro on a mini pc for evaluation purposes, the pc is 4 days old with nothing installed other than the os. Are they the only versions on the download page with Gmsh functionality? ---

Gmsh functionality is ok on another system running windows 10 that I tried so issue is not the user ! So it’s either the o/s or something about the system. Has anyone tried the gmsh functions on windows 11 ? ---

I am using windows 11. Maybe some library was removed by the antivirus software. Check the number of files in the: lib subfolder: 74 netgen subfolder: 53 ---

I’ve got the correct file counts. Netgen works fine ---

After you start the meshing a file called gmshData is created in the working directory. Can you try running GmshMesher.exe with the argument gmshData in command line as: c:.…\lib\GmshMesher.exe gmshData ---

Yes i tried this already, same error. Ckearly the issues i have are not prepomax issues. There’s something about the dll’s for gmsh and ccx\_dynamic my system doesn’t like. ---

GmshMesher.exe is an exe developed by me (a part of PrePoMax) that only calls the gmsh.dll. So this file might also be a problem. The reason a .exe is used internally instead of the .dll is that if it fails, or if it is stuck in a loop, or if the process takes too long, it can be stopped by killing the .exe process. ---

What you could try is the Dependency walker. It is a free tool to find missing .dll files. YOu can download it from here: [https://www.dependencywalker.com/](https://www.dependencywalker.com/) Open the file GmshCommon.dll, wait for a little, and then post the resulting image with the main tree collapsed. I am not an expert using this tool, but sometimes, I am lucky to find the problem. ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/d/d02db2a0023c94c444348355cd5c5e5ddcf44831.png) ---

so i hunted down the missing libraries and copied then to the lib directory, copied and renamed some where the reference dll has an extra “d” in the name, and behold… ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/5/5124fd6a446405f9948ce0b2cc9d014a0d217784.png) ---
