Yes, with W7 64 bits there is no more software for easylaunch, and therefore no way to activate the UMTS modem apparently... or thats is what I am looking for.
The "workaround" I ve found was rather to reinstall this software

But now even if software works it does not give me access to the UMTS activation....
I may end up buying external modem, this is stupid!
