Code singing
I did not know this was still causing problems but if you need a self signed driver for 64 bit Windows there are very good instructions on the technique I use here, I did not know this was a great secret but it appears after years of using this technique that it is. Microsoft I feel had no choice they needed something to force the industry to get with the program and start signing their files and if your on a budget a can not afford anything they also provided the tools free but for for those that have a budget and will be distributing there files to everyone the signing codes are not very expensive but I agree with Mark they are overkill for one off’s and personal use. So good luck.
