AinTransitions for After Effects - Troubleshooting

You may encounter a situation when you try to start the extension through the menu “Window” > “Extension” > “AinTransitions” in After Effects, but the window with the extension does not open.

This can be caused by only one reason when the After Effects on the security policy cannot launch an extension that does not match the signature. That is, this means that the extension signature is made according to the list of files at the time of the extension assembly, and if this list differs by at least one file or changing one of the files, the extension will not be launched.

For example, this situation can easily arise when you update the extension manually by replacing files, while there may be files that are no longer on the new build list and thus the signature does not match. Or for example, you accidentally added an extra file, or for example, a Finder (on Mac OS) created a system file.

The solution may be to reinstall the extension through the ZXPInstaller application so that it probably does not have extra or modified files. But there is a way in which all extensions will run without any problems, regardless of signature validation. The solution to the problem is listed below for both operating systems.
