Hi,
Try this and it worked for me:
- Open the machine's System Properties.
- Go to "Advanced" tab.
- Click on "Environment Variables" button.
- If there is no variable name "Path", create one (note: case sensitive).
- Set the value or cascade using ';' the SAPgui path. For example:
"C:\Program Files (x86)\SAP\FrontEnd\SAPgui" - Restart Vugen.
