When running from an elevated (as an Administrator) command prompt, I get:Wouldn't know about Win10 since I never used, but the code is compiled as-is from GitHub. I can vouch that nothing was modified.
If you're still paranoid you can always compile it yourself, I only posted it because people were asking for it.
What kind of error are you getting anyway? Because for example when running the tool through Cygwin it didn't work for me but runing it from regular windows commandline works fine.
The system cannot execute the specified program.
I've managed to run it on an older W7 machine tho, but alas, the converter still gives:
MobiConverter by Gericom
MOC5 container detected!
Error! Not supported yet!
Many Thanks anyways..I hope Gericom improves the decoder..
