"Access to path denied" error

QTL IciMapping software threw an error when I tried to open an input file. "Access to path denied."

Seems like there is security restriction in my folders.

1. Right click the folder that has your software or the folder that has files that you want to open.

2. Security tab

3. Highlight ALL APPLICATION PACKAGES and Edit.

4. Give it Full Control.

5. Similarly, give full control to ALL RESTRICTED APPLICATION PACKAGES.
6. Similarly, give full control to Users (YOUR_PC_NAME\Users).

7. Apply --> OK.

Should open your file now!
