Docker startup error, Unable to launch process: 1260

I have Docker running on other machines but I cannot get it to work on my main development machine. On startup it crashes with this error.

I hope I posted enough information, I am really anxious to get Docker working on this machine but I am at a loss and I haven’t been able to find anything helpful in my searches.


Did you fix this issue? i am also having same issue, do you have any solution?

I was surprised that I had not responded to this. Yes I did resolve this. The problem turned out to be a program I had installed to protect against Ransom Ware. It was one of those quirky little programs that I probably shouldn’t have installed but I did and then totally forgot about it. This program was blocking certain extensions or something like that. It was so long ago I cannot remember the name of the program but I had to do some registry edits to resolve it. When I have some time I will try and dig around and see what all I did and post it. Sorry I couldn’t help, and shame on me for not posting it at the time.
