Fix for x64 ASP.NET Applications running IIS 6.0 webserver on x64 Windows

If you ever happen across an IIS web server that absolutely REFUSES to behave properly and render web application requests for clients as a good little web server should, then check out the fix for x64 ASP.NET 2.0…

1) Check that you DO NOT see this:

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis -lv

2.0.50727.0     Valid           C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll

1.1.4322.0      Valid           C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll

2.0.50727.0     Valid           C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\\aspnet_isapi.dll

2) If you do, then do this:

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis -ua

Start uninstalling all versions of ASP.NET.

..............................Start uninstalling all versions of ASP.NET.

.........................

Finished uninstalling all versions of ASP.NET.

.

Finished uninstalling all versions of ASP.NET.

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis -lv

Cannot find any installed version.

3) Finally, to make your IIS 6.0 webserver host on a X64 Windows OS, do this:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322>aspnet_regiis -i

Start installing ASP.NET (1.1.4322.0).

Finished installing ASP.NET (1.1.4322.0).

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322>aspnet_regiis -lv

1.1.4322.0      Valid (Root)    C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll

4) And also this to set x64 ASP.NET as the default and root version to finally resolve the version conflicts:

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis.exe -i

Start installing ASP.NET (2.0.50727).

.............................................

Finished installing ASP.NET (2.0.50727).

C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727>aspnet_regiis.exe -lv

2.0.50727.0     Valid (Root)    C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll

1.1.4322.0      Valid           C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_isapi.dll
