If you search the forums here you should find a thread for updating your U3 to Windows 7.  The update should be run on a Windows XP machine.  But I don’t think it supports 64bit Win 7.

Be sure you backup your data before doing the upgrade.

Another possibility would be to;

Remove U3.  It’s an option on the U3 menu.

Install the new SanDisk SecureAccess app.  http://forums.sandisk.com/t5/Cruzer-flash-drives-Solid-State/SanDisk-SecureAccess-Password-and-encryption-software/td-p/217852
