cannot find data on sandisk

Hi all,  our computer crashed and we had our quickbooks data all saved onto a sandisk 4 GB.  We bought a new computer - now Windows 7 (previous XP). When I insert the sandisk it does not launch or ask for password.  Cannot restore the backup.  Help

Since you said the word “password” I will assume you have a U3 USB drive.  If the U3 CD is recognized by Windows 7 open it and find the LaunchU3.exe file.  RIGHT click on it and then click on Properties.  Click on the Compatibility tab, click on the Run this program in compatibility mode and select Windows Vista (SP2).  Then click on the Run this program as an admin.  Click on Apply then click on OK.

Then dbl click on LaunchU3.exe.
