A couple of months ago I installed Windows 7 Ultimate N edition (64-bit). Everything went fine, but recently I've been getting activation pop-ups, warning me of counterfeit hardware, etc. I found three versions of the 7Loader and tried all three, but none of them had the desired effect - every time windows reboots I continue to get the activation warning. I googled 7Loader and came upon the latest version of the app, 1.7.7r, but when I run it it tells me to uninstall previous cracks. Going back to the other versions I had (1.5-1.6) only 1.5 appears to still be installed. However, when I click uninstall windows reboots as usual but 1.7.7 still tells me to uninstall a previous crack, and 1.5 still appears to be installed. SO, is there some known issue with the loaders? Is there another way to try to uninstall 1.5? OR, are the loaders completely incompatible with Ultimate N edition? If so, are there any alternatives to having to do a complete re-installation with another version? I've googled my issues but it appears nobody cares/knows about the N edition. Thanks for your help.
