RSA KEY Encryption/Decryption Problem

I tried

C:\dev>aspnet_regiis -pc "NetFrameworkConfigurationKey" -exp

Creating RSA Key container...

The RSA key container could not be opened.

Failed!

and

C:\dev>aspnet_regiis -pa "NetFrameworkConfigurationKey" "ASPNET"

Adding ACL 开发者_Go百科for access to the RSA Key container...

The RSA key container was not found.

Failed!

Both failed. Any idea?

In general when we have had to generate these keys we have needed somebody who had admin level permissions to generate the said key.
