Troubleshooting vCAC installation issue: Could not load type ‘system.servicemodel.activation.httpmodule’ from assembly ‘system.servicemodel’

A quick post about solving the “Could not load type ‘system.servicemodel.activation.httpmodule’ from assembly ‘system.servicemodel’” error after installing the vCloud Automation Center 5.1 on a Windows 2008 R2 machine.

If you successfully installed vCAC but IIS on your Windows machine is unavailable and you get the error mentioned above when you browse the default IIS web page then you probably need to re-register the .NET framework. To do this follow these steps:

1. Open the command prompt as an administrator.
2. Browse to C:WINDOWSMicrosoft.NETFramework<Framework_Version>
3. Type the following: C:>aspnet_regiis.exe –iru
4. Reset IIS by typing: C:>iisreset
5. Close the command prompt

Done.

The default IIS page should now load normally.

Cheers!
