Windows 7, 64 Bit, Couldn't install 1603

[srlawton]

I've been having the 1603 problem and just couldn't get Paint.Net to update itself. 

 

This morning my iTunes also refused to update itself.  Looking into the problem, I did the following:

 

Goto:

 

1. C:\Users\xxx\AppData\Roaming\Microsoft\Crypto\RSA

 

2. Delete the content in the above location.

 

 

If in doubt, move the contents somewhere else.

 

Afterwards, both Paint.Net and iTunes installed.
