Scheduling a .tas gives me "The File Exists. (Exception from HRESULT: 0x80070050) "

Looking at some forum posts I see that there has been a solution to clear the temp folder, create a read only tmp file and try again.

Unfortunately this hasn't worked and when I try to reschedule a task, I still see this error.

I had a similar task scheduled with win 10 Task Scheduler and deleted that in case there was a conflict however I cannot schedule the tas file to run automatically.

I have seen that this error is common with sharepoint but I'm not connecting to a sharepoint system in anyway that I am aware of.

If you have overcome this please let me know how so I can try to do the same.
Thanks in advance.
