It looks like there are files from an old install left over. If you tested tmm at all make sure you delete the jar you added or just delete the entire install folder manually and reinstall

Had the same problem. A simple uninstall reinstall did not work had to remove/delete install folder after an uninstall. Finally got it to work. Thanks for the help.

Restart PC then Uninstall(like executing the uninstaller not just install the new, also make sure the folder of the program is gone after that, tick the checkbox to install all) and install whatever version you like.
