The last version of MBlock does not support Windows 10 as stated in the release notes: http://www.mblock.cc//c-page-a-run-id-13.html Is there a link to 3.0 I can use or are people having good luck running 3.1 under Windows 10. Thanks!
MBlock 3.1 and Windows 10
I’m using mBlock 3.2 (released 1/5/16) on Windows 10, and it works for me! http://www.mblock.cc/download/
