Technocad 15.8 error message.

Question

I have issues with circle files opening in TechnoCAD 15.8 Windows 7 Professional 64bit. Any suggestion? I get the error message "The document is already in use" or "Encountered an improper argument".

Answer 1

To fix the first error, make sure that the file is not opened in another application. Close all the running applications while TechnoCAD is launched. As for the second error, make sure that the file you are trying to open is compatible with TechnoCAD. Sometimes these ambiguous error messages are related to the content that needs to be handled by the application.
