Restarted Royal in non-elevated mode. See screenshot from task manager. Not elevated and error message is present.
So there seems to be a permission problem though. Unless you start Royal TS elevated, you are not able to access process information of a child process started by Royal TS. I'm honestly not sure how this can happen on your system's. Maybe some policy? Is this a domain user logging on to a domain joined machine? Maybe you can try with a local user account?
This error comes both on a Business domain joined computer, and the one im using now, a private Win10 computer without any domain related settings. A standard login through a Microsoft account.
I too use a Microsoft account to log on to my machine but I can't repro the issue. Any other tool/software which comes to mind?
is it possible that you are starting putty out of a onedrive folder?
check my response here:
A quick search with google showed that other users are also having issues running executables from OneDrive. I haven't found a solid answer or guide to enable that though. Some articles are quite old and I don't know if they still apply.
