Hello Sundar,

I get the same error when I set the Strong Name tool to use a
Cryptographic Service Provider other than the default using "sn -c
<CSP-name>". When I reset the Strong Name tool using "sn -c", which
resets the tool, it works again.

I also believe to have discovered that the folder "C:\Documents and
Settings\All Users\Application
Data\Microsoft\Crypto\RSA\MachineKeys" is only used to store keys in
containers (there is a file for each container you create via "sn -i
<keyfile> <container-name>")

I hope this helps.

Greetings, Beat
