Trying to install WCF with IIS7 and Net Framework 4.0

When I run my WCF service in my localhost I get the following error:

HTTP 404.3 - Not Found with and error code 0x80070032.

Right now I'm trying to install WCF by running ServiceModelReg.exe -ia in folder:

C:\Windows\Microsoft.Net\Framework\v4.0.30319

In command prompt I get an error saying ServiceModelReg.exe does not support WOW mode

What does it mean and how can I install WCF?

Solution

Go to folder:

C:\Windows\Microsoft.Net\Framework64\v4.0.30319

and try again.
