Trying to upgrade a Dell with an Ultimate N 6300 under Win 7 Pro from v15.3 to current v15.6.1.
When I run the upgrade file [either full 75M+ or drivers only] it tells me it can't upgrade from that version and I need to manually uninstall the drivers.
I've tried:
1) going into control panel and uninstalling from there. It successfully uninstalls, but the new driver file still refuses to upgrade.
2) Going into device manager and uninstalling the drivers while checking the "delete drivers" checkbox. I've done this all the way to the point where Win7 complains that there are no drivers for the device. The 15.6.1 still refuses to install, demanding I manually uninstall the existing drivers.
Meanwhile, the 15.3 package installs from any point.
Am I missing something? Is there a command line switch to force the install?
Thanks.
