Installing error

Hi
When I try to update the program, the error "error writing to file.... Verify that you have...." appears.
When I go to the indicated directory and create any file, txt, I can do it, so I can access, create and write to the directory.
What can I do to update without first uninstalling the program?
Thanks in advance
Regards
