TPToolbox stuck on "Checking novacom service ..." topic

I've got java and novacom installed. The novacom service is running. The TP is connected and in the right mode. I'm on Windows 7 64bit, a fresh install since I last used TPToolbox, but it's the same OS... This is driving me nuts. I've tried three different versions of TPToobox and various other random things I could think of.

[Q] Install Novacom Jar on Windows 10 topic

Anyone out there installed Novacom on any of these Windows 10 preview builds? I've tried running the JAR file that's out there, but I run into an error:

ERROR: Driver Installation Failed

There are not compatibiility settings for .jar files like .exe files.

Any ideas?
