2. Inside the TeamViewer options menu, select the Advanced tab from the left-hand side menu.
3. With the Advanced tab selected, move to the right-hand side menu and click on Show advanced options to make the hidden settings visible.
4. Once the Advanced options menu is visible, scroll down to Advanced settings for connections to this computer and modify the drop-down menu associated with Access Control to Full Access.
5. Save the settings by clicking the Ok button.
6. Restart Teamviewer on both computers and see if the issue has been resolved.
