How do i set it up?

First of all, download the latest version from http://sourceforge.net/projects/aspsysinfo/.

Unpack it with rar into an existing directory on your webserver, or create a virtual one where you put it.

Register the components in ./components/ (if your aspSysInfo-dir is c:\inetpub\wwwroot\aspsysinfo\, you would use `regsvr32 c:\inetpub\wwwroot\aspsysinfo\components\SystemInfo.dll` and `regsvr32 c:\inetpub\wwwroot\aspsysinfo\components\Reg.dll`) and check that there are no error-messages.

This is all you need to do for a basic setup, feel free to browse index.asp if you want to edit things, but if you're not knowledgeable with ASP, stay away from the bottom part ;)
