The post discusses reasons behind the TeamViewer connect button being greyed out or not clickable and offers clear solutions for Windows and outgoing connection problems.
The TeamViewer connect button sometimes appears greyed out, and this usually points to problems with your account, software version, network, or access settings. When this happens, TeamViewer cannot confirm the requirements needed to start a remote session, so the button remains unavailable. Knowing the common causes helps explain why the issue appears and what situations are linked to it.
| Cause | Description |
|---|---|
| Not signed in | TeamViewer limits some actions when the user is not logged in. |
| Outdated version | Older versions may contain bugs that disable the button. |
| Corrupt installation | Damaged files can stop TeamViewer features from working. |
| Network restrictions | A weak or blocked connection prevents the button from activating. |
| Commercial use detected | The free version may be limited if TeamViewer detects business-related use. |
The connect button often stays inactive when you are not signed in to your TeamViewer account. Logging in helps the program verify your license and permissions. An outdated version may also cause the button to fail, so the latest update is helpful for stability. If the installation becomes damaged, a reinstall can clear broken files and restore normal functions. Some free users may also see restrictions when the system detects possible commercial use. The next section will share how to fix this issue.
Sometimes, the connection may fail because the device you are trying to connect to is denying any incoming remote control sessions. You need to give full access to computers connecting to this device.
Go to Options (on the top right corner) > Advanced. Under Advanced settings for connections to this computer, choose Full Access. Besides, check Full access control when a partner is connecting to the Windows login screen box.
A corrupted TeamViewer file on your computer may be responsible for the TeamViewer not connecting error. Removing this file from your system may help resolve the issue.
Step 1. Press Win + E to launch Windows Explorer.
Step 2. Navigate to the "View" tab and check the box for "Hidden items."
Step 3. Go to the specified file path and open the "hosts" file using Notepad.
Step 4. Press Ctrl + F, type "TeamViewer," and click "Find Next."
Step 5. If no results appear, there are no corrupt TeamViewer files on your PC. If you see entries like "#TeamViewer," right-click them and delete them.
Step 6. Press Ctrl + S to save the file, close Notepad, and check if the connection issue is resolved.
If you're still facing the "TeamViewer not connected" issue, try resetting the "Assignment" settings on the remote PC. Many users have found this solution helpful.

Step 3. While in this section, also enable the "Manage this device" option to ensure it appears automatically in your contact list.
Step 4. Click OK to save the changes.
