Source SDK Hammer not launching

My settings for sdk are as below:

When I double click hammer editor the windows loading icon on my cursor appears for a split second and then disappears. There is no error message.
It does not launch, I have tried reinstalling sdk and deleteing all of the sdk files in the steam directory.

Any solutions?

Garry’s Mod has been having some troubles to get it correctly configured.

The way I did the configuration is like you.

Mine does launch fine, however, there is a terrible lag, so I do not recommend you to use the Source SDK.

There is an alternative way to fix this issue, you can use the SDK 2013 in order to make it run.

Still not launching, has been a day now.

Where can I get a copy of 2013 SDK?
