Good find Only I have to ask because it's little unclear to me. Did you mean when you said, `the compile worked without SP1 installed´ That the RakGS dll was compiled correctly, and this build runs on PC without VC/SP1 installed!?

In other words. Any programmer working on plugins for Lite-C could run into the same problem. In the case they have SP1 installed, compile a dll. And then have it distribute to end-user(s) who doesn't have VC/SP1 installed?

Also about those two missing files especially EFSADU.DLL (File Encryption is used by the Encrypted File System EFS. This is used for encrypting files or directories in Windows 2000 and above). You said they are belong to Windows XP Professional. Does this mean that encryption feature from RakGS is only available when the end-user is running Windows XP Pro? Sorry if I misunderstood.
