Same problem:
Update the client and client is not starting. In Taskmanger i found GameJoltClient.exe but i cant open the client in any way. I killed all tasks, uninstall the client and delete all files of the app in the ...AppData\Local\GameJoltClient folder.
I donloaded new client from web, install it and the same ...! client does not start after setup, only some GameJoltClient.exe in the taskmanager.
Running on Windows 7 and Application manifest of GameJoltClient.exe tells me OS is supportet.

EDIT: If i run ...AppData\Local\GameJoltClient\data-376715-1238258\notification_helper.exe i get this Error Message:
"Das Programm kann nicht gestartet werden, da api-ms-win-core-winrt-error-l1-1-0.dll auf dem Computer fehlt. Installieren Sie das Programm erneut, um das Problem zu beheben."
Theree is also a debug.log in the folder:
