I got an odd error today regarding the file C:\Program Files\Common Files\Microsoft Shared\ClickToRun\ClickToRun.exe: The device did not have the permissions to run (or something, I closed the prompt before getting a screenshot)
I was not using any Office product, nor had I since my last reboot. I searched for information regarding this file, and there is not enough information regarding the provenance of my specific file. I've checked HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run and the Task Manager startup tab, but there's no indication I have any unknown system startups. I know the file is sometimes a legitimate file, but the fact that it threw an error when I was not interacting with Windows products worries me.
What are the chances that this file is actually malware?
Update:
This MS Answers forum answer includes the exact error, which is "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." This seems to imply that the file doesn't exist, when I can clearly locate the file.
If another of this error pops up, I'll screenshot it.

If you have any pending office updates (mentioned under the 'Product Information' section on the Office product's 'Account' screen) do you experience the same error when selecting the following 'Update Now' option?:
If so, running a quick repair, via the change option under Programs and Features, may stop the error appearing and allow the pending update to be downloaded and applied.
