I don't know why but I cant install the adb.exe I have this issue :
And in game maker this issue:
What's odd is that at the beginning it recognized me the android SDK, and after a few builds it stopped working.
Please help.
I would recommend seeing if that service is actually running and has already been installed, in which I would: Kill it. Restart SDK manager. Try installing it again. Based on this information here: Error: Stopping ADB Server Failed (Code -1) {Installing API's - Android SDK}
