Where TeamViewer fits
Use it when both parties have agreed on a remote support session.
Check before you choose
Verify session requests and check the license conditions for professional use.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Identify the problem before installing a utility. File search, remote support, hardware inspection and bootable media preparation need different permissions and can affect the computer in different ways.
