Unable to access Remote Desktop Web Access Site - HTTP 500 -

Remote Dekstop web access is not accessible after installing .net 1.1 which was bundled with a program.
I have uninstalled .net 1.1, but am still having the issue.
I have ran a repair on .net 4.0 - same issue.
This is the error I get when I try to browse to the site from the server.
 Error from browsing to the page from IISHTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Windows\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll" failed

Looks like I got it figured out.
I ran the following command.
C:\windows\microsoft.net\framework\v4.0.30319\aspnet_regiis -ua
-this uninstalled all .net versions from iis
-I got errors on this, 0x80004005, but i disregarded them and carried on.
-after that was finish I ran the following command.
C:\windows\microsoft.net\framework64\v4.0.30319\aspnet_regiis -r
-this renistalled .net for iis
-the directories are different from the uninstall and reinstall. I got an error for rdweb after running this on just Framework and not Framework64. So just run it on 64 for both if you can, this is just what worked for me.
Then I totally reinstalled RDWEB, from remove role service in the Server Management console.
Everything is working now.
I can browse to the page without error. Just had to reconfigure my apps.

Don't know if you ran a repair on installer or via commandline. Typically, these issues are caused by mismatched tags.

Try the following.

1. Open a command prompt in administrator mode.
2. Browse to C:\Windows\Microsoft.NET\Framework\v4.0.30319\
3. run aspnet_regiis -r

If this doesn't help please provide the OS, (32/64) and your application Pool configuration for further corrections.

The repair on .net 4 was done through add/remove programs.
Ran this command as an administrator without problem. Still having the same issue.
