Steps to reproduce: 1.Create WPF test and select Configure 2. In the WPF Application path enter something like %wpf%\AvalonCalculator2.exe (this is a valid path since I can access it in Windows Explorer by typing %wpf% in the address bar) 3. Click the record dropdown and select Launch new recording application instance. Expected behavior: The file path is accepted by Test Studio so you can start recording Actual behavior: You get the error: Unable to launch recorder: path %wpf%\AvalonCalculator2.exe is not valid. Please configure the test with valid path to the WPF application. Refer to the screenshot attached.
