Snagit (Windows): Outputs/accessories will not install

Problem

Receiving an error, or nothing happens when I try to install Snagit outputs/accessories.

Solutions

We have identified 3 different causes for this behavior. Each are explained below. Please note, that it is possible to be running into more than one of these at the same time. For example cause 1 combined with cause 2.

 

Cause 1: McAfee Security

We have found that McAfee has been causing us some installation problems with their new versions. If you have McAfee installed you will want to do the following before installing Snagit (or any accessories):

  1. First go to your system tray and right click on the McAfee Icon then please choose Change settings >> Real-time Scanning as shown in the image below.



  2. After the McAfee window opens up, you will want to click on the Turn off button as shown in the image below: 



  3. After you click Turn Off, you will get a popup asking how long you want to turn the service off.  This is mostly a preference and computer based setting. If you need a long amount of time to complete the installation, you can choose "When I restart my PC."  After you select the length, you can click Turn Off. 



  4. After you have completed this, you will need to restart Snagit completely. Hover over the top of the Snagit capture window (blue bar in 12 or red circle in 11) then click on the gear icon and then choose Exit Snagit. Please also make sure the editor is closed as well.
  5. Start Snagit again from your start menu and then try to do the installation of the accessories you were having a problem with. It should complete the installation now without error. 

Cause 2: Browsers

Some browsers change the extension to .zip - when this happens they will not immediately install. Follow these steps to correct the issue:

Snagit 2018 and later

  • Right click on the downloaded output/accessory and choose Rename. 
  • Change the extension from .zip to .tscplugin
  • Double click the file again and see if it works

Snagit 13 and earlier

  • Right click on the downloaded output/accessory and choose Rename. 
  • Change the extension from .zip to .snagacc
  • Double click the file again and see if it works

Note: If you do not see extensions on your files, you may have to go to Start > Control Panel > Folder Options > View tab and un-check "Hide extensions for known file types."

Cause 3: Snagit Bug in 13.0.2

To fix the problem, install the latest update by opening Snagit and browsing to the file menu Help > Check for updates.
