It's likely Comodo Firewall causing the problem. Another user had the same problem with it:
Unable to launch
Comodo Firewall attaches to Spine's process and mucks around with things even if Comodo Firewall is disabled. That is quite nasty behavior, especially for what is supposed to be a firewall. You said you can't install it, is that because you need a software firewall? If so I can suggest using Windows Firewall Control instead, as I mentioned in that thread.
We have had lots and lots of problems with antivirus wrecking Spine. Sometimes they prevent Spine from running at all. Sometimes they let most of Spine work, but break some parts so it crashes later. Sometimes they let Spine run for a while, then delete or modify Spine's files later. When this stuff is happening, it creates a lot of noise for us. It becomes difficult or impossible for us to tell whether a crash is because there is a legitimate problem we need to fix, or if an antivirus has caused the problem. Users suffer crashes and other problems, contact us about them, and it takes a lot of our time to research the issues.
That is why it's much better to know that other software is poking holes in Spine so it can be fixed up front. Running software that mucks around in every application running on your computer is generally a bad idea. It causes problems with other software, it slows everything that runs on the computer, and it provides very little to no actual protection.
I know you are having a specific problem and would like to solve that. I expect uninstalling Comodo will be sufficient, so I hope that is possible. I doubt UltraMon is a problem. Process Monitor logs a whole lot of stuff for many reasons and not all of it is not important.
