Question - IDE Error when trying to run game

I get the following error when trying to run my game:

Permission Error : Unable to obtain permission to execute

IDE version:

The game runs when using the most up to date runtime. The reason I'm trying to run with an older runtime is because I have glitches with the most recent runtime, andI want to pin point at which version of the runtime do the bugs start to appear.



I also had that problem a while ago. You can use latest IDE and runtime by disabling this option:
Preferences -> General Settings -> Compiling -> Show compiler commands in compile output.
