Hey speters1,
You can take ownership of the file either by command ...
Takeown /f "C:\ ... .dlr"
(Must be ran from elevated command prompt)
Or by going to the file, right clicking on it, select properties, go to the security tab and click advanced, click the owner tab, click edit, click either your username or administrators and click OK.
This should give you the permission you need.
Good Luck
