This Software Key Is Not Valid

License Keys are Version Specific

You will need to download the correct version for your license key. If you are unsure which version you own, please follow the steps in this article: How to check what version your key is for.

Confirm the Key is Entered Correctly

There are some recommendations in entering the correct key in the software.

  • Make sure there are no empty spaces at the beginning or end of the key.
  • Copy and paste the entire key instead of entering it manually.
  • If you type in the key, verify you are typing all occurrences of the number zero as 0 and not the letter o.
  • Current versions (single and multi-user) of Snagit and Camtasia use a 25 character key (ie: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX).

2. Click on your Finder and then click the Go menu at the top.  Then click on Go to Folder
3. Type in the following Location and press enter: /Users/Shared/TechSmith/Camtasia/
4. Delete the License folder
5. Relaunch Camtasia and re-enter your license key.
**To find Activity Monitor on a Mac, go to your Applications folder > Utilities folder, and then double-click Activity Monitor. There you'll see a simple app with five tabs, and a list of entries that changes every few seconds.
