Problem installing SSL on domain

[AvocentX]

I am trying to install a Geotrust True BusinessID with EV, but keep getting this error in the CA Certificate part of Plesk Certificate Setup page:

Unable to set the CA certificate: Unable to put certificate file: Unable to update certificate in Web Server: websrvmng failed: Certificate::Read failed

I have followed Geotrust instructions, but the errror sounds like something server sided?
I should add that I made the certificate requesting using the subdomain on the main domain account.

Looks like that problem related to incorrect permissions (READ) for C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys\ folder. Did you check it?

What account needs Read rights on the folder?
