SInce I installed ATIH 2012 trial version, my Datatraveller 100 G2 (16Go) are not regonized by my windows 7 64bits.
Each time I plug it, it last long before the keys appear and I get message "disk not formatted" , if I want to format it, formatting is impossible because keys are "locked" and "unplug".
I have to unsinstall ATIH 2012 and restore the system , then my USB keys are working well again.
They work fine as well on other PCs I have 2 others desktop Windows 7 64bits and 1 laptop windows 7 32bits
I made a test with ATIH 2010 trial version, all work fine.
I would have buy a 3PC licence but without any solution on this issue I have at least to postpone my purchase, maybe to cancel it definitively if no solution is found.
