Hi, I just installed Gnuradio 3.8.0.0 (Python 2.7.10) from the website. The most simple application with gnuradio fails with
>>> Done (return code -1073741795) and no windows appears. This is how it looks: https://snipboard.io/o4ZjvA.jpg When I add a USRP block I run into the same trouble but this time with a slighly different negative return value: Executing: C:\Program Files\GNURadio-3.8\gr-python27\python.exe -u X:\Prototype\gnuradio\SaveSignal.py [INFO] [UHD] Win32; Microsoft Visual C++ version 14.0; Boost_106000; UHD_3.14.1.HEAD-0-g0347a6d8 [INFO] [X300] X300 initialization sequence...

I know Windows is not officially supported and it is marked as "v3.8.0.0/v1.7 BETA" but I would still be happy if this can be resolved/debugged somehow. Thanks, Luke
