To set "Read" permission;
- Right click on the folder that is having trouble compressing files and go to Properties.
- On the Security tab, click Edit to change the permissions.
- Select the admin user in the Group or User Names section.
- Put a checkmark on Allow full control.
If the above fails to solve the problem, you could try using the free 7 Zip and see if that works. You can download from the link below.
