I just installed on PC Windows 7 Home Premium - Adobe Edge Inspect and Chrome extension.
On Samsung Galaxy Tab 2 10.1 I installed Adobe Edge Inspect CC.
PC shows "Waiting for connection".
Samsung show continous spin of gif.
No connection takes place.
I tried manual connect but got message "unsuccessful" but no error code.
Unable to use this software.
(I read where Mac had problems but answer not appropriate for PC)
Here's a few things to check on:
Once you've checked all those things, click the manual connection button on your device and type in the IP address of the computer running Edge Inspect. You can find that IP address at the top of the Edge Inspect Chrome Extension dialog.
Let me know how that goes,
