The solution for the "Cryptographic service provider (CSP) could not be found for this algorithm " problem is to uninstall the previous versions of .NET framework and install 1.1 .NET framework from the Microsoft website. Atleast this worked for me.


I downloaded the 1.1 .NET framework from:
http://www.microsoft.com/downloads/d...displaylang=en

Google Search: Microsoft .NET Framework Version 1.1 Redistributable Package

Thanks
