64 bit and asp.net makes problems

[Guest]

Following configuration:

Hardware:

64 bit system (amd athlon 64 bit 3000+)

Software:

Windows 2003 Standard Edition x64 version. ASP.net 2.0 (x64 version) is
installed on this system.

Problem:

The 64 bit aspnet_isapi.dll doesn't work! I've assigned the file extensions
..aspx, .asax, .ascx, .cs, .config with the 64 bit aspnet_isapi.dll file
(C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll), and
activated it in the web server extensions panel. If I try to access the
website, I get an 500 server error (internal server error).

It works fine with the 32 bit version of aspnet_isapi.dll
(C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll)

Try registering ASP.Net from 64 bit folder by running aspnet_regiis script
from that folder.
