[USB Flash Memory Stick won´t work at new vista machine]

Thanks to Paraglider for the great advice. I had same problem with Vista Ultimate not registering my Store n Go. Your instructions worked like a charm!

Try the following steps ( it will be easier if UAC is disabled ):

1) Unplug your USB device

2) delete all files with an extension of pnf from c:\windows\inf ( be very careful only to delete the pnf files ).

3) delete the file named infcache.1 from c:\windows\inf. You will need to modify the file permissions of infcache.1 to give the Users group full control to do this. From explorer right click on the file and choose properties. Select the Security tab. Select the Edit button. From the Group / Users list select Users.In the 'Permissions For Users' box select Full Control. Then Apply. You will get a warning - select Yes. Then hit OK twice. You should now be able to delete the file INFCACHE.1. Make sure you only delete this one file.

4) Plug in your USB device. It should now install.

Be very careful when performing steps 2) and 3).
