Access Denied on Create Self-Signed Certificate

So, While creating a self signed certificate, I got "Access denied" error message.







I was logged in with my admin account, but I still need to grant "Modify"  rights on RSA/Crypto folder.

BTW, In 2008 R2, RSA folder is in c:\ProgramData\Microsoft\Crypto\RSA, and needless to say ProgramData is a hidden folder
