iOS Question hanging problem in B4i in the during of .cer file creation


Licensed User

I use b4i 3.5 on win 10 64bit. Also, I use Mac with Xcode 6.x. I faced with a strange problem during of the configuration of b4i on my windows. After setting of Path Configuration, whenever I try to create a new Private Sign Key, B4i only can create B4i.p12,B4i.keystore and push.dat, but it does not create .cer file and it hangs!
What should I do?
