问题
I have been trying to get Python 3 installed, but this error occurs:
I am running it on Windows 8 64-bit. I will keep trying. Thanks for the help. I didn't find any articles on the matter, so I came here.

I encounterd this problem for all applications, meaning that when I tried to install an application the same error will pop up "keyset as registered is invalid".
The solution for me was to delete the folder
S-1-5-21-3065067753-4167832549-3323262698-1001
found here:
%AppData%\Microsoft\Crypto\RSA
Please make a copy of it before you try it
