I am running Ignition 1.1.1 and I’m having an issue with one of my computers not being able to open the client or designer. I am getting this error message, but I do not know what other program would be using this executable. Has anyone experienced this, or know where I should look to fix this.

There is also another error that I have come across: ![ffythynndghgh](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/c/cc3d936b7f79b157c7dd1c7d8ed9e07383b77f7a.png)

Try deleting that entire “11.0.7” folder and launching again.

I gave that a shot, but once it gets back to the runtime step it will still give me the same error.

Hmm. There might be some kind of AV software interfering then.
