If you are unable to install an add-on from a zip file in Kodi, you can try the following solutions:
Solution 1: Check the Zip File
• Make sure that the zip file you are trying to install is compatible with your version of Kodi. Some add-ons may not be compatible with the latest version of Kodi, so you may need to find an older version of the add-on.
Solution 2: Check the File Path
• Make sure that the file path to the zip file is correct. You can check the file path by going to the "File manager" in Kodi and verifying that the path is correct.
Solution 3: Clear the Cache
• Clear the cache of the add-on you are trying to install. To do this, go to "Settings" > "Add-ons" > "My add-ons" > "All" > select the add-on > "Clear cache."
Solution 4: Allow Unknown Sources
• Make sure that the "Unknown sources" option is enabled in Kodi. To do this, go to "Settings" > "System" > "Add-ons" > "Unknown sources" and turn it on.
Solution 5: Disable Antivirus or Firewall
• Disable your antivirus or firewall temporarily as they may be blocking the installation process. Once you have installed the add-on, you can enable them again.
Solution 6: Rename the Zip File
• Try renaming the zip file to a shorter name or a name with no spaces or special characters.
Solution 7: Try a Different Repository
• If you are still unable to install the add-on, try downloading the zip file from a different repository or source. Try these solutions one by one and see if it resolves the issue.
