I just instaled XP Mode from Windows Site : Folow the link
(Works only with Pro and Ultimate versions of Windows 7)
Then, I ran all the upgrades for XP Under the XP mode...
Now, instal The Variax software from the CD on XP mode...
When it come to the driver instalation, you will have to mount the USB device from a menu at the top of the screen before windows XP emulation can find it.
Proceed with all the Upgrade Ask in the Line 6 Monkey...
During the last Upgrade of workbench 1.58 , Java wont be able to instal. This maybe du to a broken link on the Java site. Anyway, you can get it here :
Java wil ask you to upgrade on other start up... It's ok, everyting will still work.
I Wish this will help some of you..
