http://en.wikipedia.org/wiki/TuxGuitar This is part of the problem. Lot of the past users of that program have moved on with a little bit of work TuxGuitar will feature pass Guitar Pro. http://en.wikipedia.org/wiki/Comparison_of_scorewriters There is a nice list of open source onces out there. Have you tried with a WINEARCH=win32 prefix. Also in the bug report does not seem to be a report just plain from wine output without tweaking debuging options. Error also says program is being odd for some reason "C:/Program Files/Guitar Pro 6" Those slashes are the wrong way to convention for windows. Might be clue to the error. Did you clean install in 1.1.42 and 1.2. I have had cases where its a form of install error. Ie installed under X version wine works. Installed under different versions does not work. Same with the runtime dependance those are need in before.
