Chilkat RSA Encrypt fails in Windows7/IIS7

[JiNx]

I developed a simple ASP.NET website that uses Chilkatdotnet2 (version 9.0.8.0) to generate RSA Public/Private Key pair used for encryption. Below is the sample code\[code\] bool success; string UnlockChilkatRSA = "XXXXXXXXXXXXXX"; int RSAKeyLength = 1024; Chilkat.Rsa rsa = new Chilkat.Rsa(); success = rsa.UnlockComponent(UnlockChilkatRSA); if (!success) { lblmsg.Text = "RSA component unlock failed"; return; } success = rsa.GenerateKey(RSAKeyLength); if (!success) { lblmsg.Text = rsa.LastErrorText; return; } string publicKey = rsa.ExportPublicKey(); string privateKey = rsa.ExportPrivateKey();\[/code\]This works well when I host my web in Windows Server 2003 (IIS6), but when I tried to host it on Windows7 (IIS7), this line of code \[code\]success = rsa.GenerateKey(RSAKeyLength);\[/code\] doesnt work and cause the web to freeze. Anyone has experience the same issue, any feedback would be appreciated.
