[Design+] Encountered an improper argument/Attempted an unsupported operation.
When I run Design +, it fails with an error message
"Encountered an improper argument." or "Attempted an unsupported operation."
The error appears when Vector Draw VectorDraw Lite File Converter 3.x program is not installed. The problem is solved by reinstalling the "Vectordraw lite file converter 3.x"installer provided in the installation file.
1. Enter the path where Vector Draw is installed > Run VdLiteFileConverter.exe
C:\Program Files\MIDAS\midas Gen\Vector Draw
2. Install Vector Draw > Reboot computer
