Permission denied

Hi,

The permission denied error normally appears if you are not using the admin account to run a specific program. To help us identify the appropriate solution to your concern, we'd like to ask for additional information. Kindly answer the following:

• Are you running the program as administrator when the error appeared?
• What build and version of Windows 10 are you using?
• Can you please show us a screenshot of the error message?
• What troubleshooting steps have you tried so far?

We hope to hear from you soon.
