In case you have problems with the setup files for ASP.NET Debugger Extension you can manually install the module.
All the files are in this zip file.
Getting Files In Place
To get ADE.dll in the GAC (Global Assembly Cache) you can just drop it in the c:\windows\assembly folder.
You need ADEWOWHelper.exe only on x64 machines. Or you can skip this file. You need to drop the ADEWOWHelper.exe and MdbgCore.dll in the c:\windows\system32\inetsrv folder.
Registering the module to show up in IIS Manager
You need to edit the administration.config so that ADE will show up in the IIS Manager.
Stop the WAS service so that the file is not locked
net stop WAS /y
Open the file C:\Windows\System32\inetsrv\config\administration.config in notepad ( You need “Run as administrator”)
You need to edit two sections <modulesProvider> and <modules>
In the <moduleProviders> section add
<add name="ADE" type="vijaysk.adeModuleProvider, ADE, Version=126.96.36.199, Culture=neutral, PublicKeyToken=83baeac24a5b6379" />
In the <modules> section you need to add
<add name="ADE" />
Start your WAS and IIS services and open a new instance of IIS.
To uninstall you can remove the files and the entries in the administration.config
