I cannot update my MAMP PRO 6.1, 6.3, 6.6.3

This is a known problem of these versions. To resolve this problem, proceed as follows:

  1. Please download a new complete download package here: https://www.mamp.info/en/downloads/
  2. Do not uninstall the software! Simply install the new version over the previous installation and everything will work as before.
  3. Also, you can update it through the app using the "Check for Updates" option in our app.
