RD is actively investigating the cause of the issue. Since the issue is specific to some computers, we have not identified what the real cause is. We suspect it may be related to the Save dialog UI. Would you please try the following method and let us know if it helps:
1. Make sure your current installation have IC2023PU1_SP2
2. Copy the attached dlls and paste to replace the ones in your IC2023 installation bin folder such as C:\Program Files\IronCAD\2023\bin
3. Add the following registry and set value =1, (NotUseVistaUI, set its value =1 ) (I attached a video showing how to edit the Registry)
4. Then start IronCAD to test and let us know you still have same issues of explorer when running IronCAD.ISEngineAfx.zip
