Common Extensibility Platform not loading. AE won't start

when I try to launch After Effects I get an error saying it can't continue due the the Common Extensibility Platform not loading. Ive looked up and tried all possible solutions and still hasn't worked. Everything from reinstalling to granting Read/Write permissions and still does not launch.

    Hi there,


    Sorry to hear about your issue. What are your system specifications (CP, GPU, RAM, OS version)? In addition to what the expert suggested, try running After Effects as administrator (right-click its icon and select Run as administrator) if you're on Windows.

    Let us know the outcome.


    Thanks,

    Nishu

    Was AE working previously? If you feel that you’ve done all possible solutions you may want to consider using the Adobe Cleaner tool as a last resort. Please be fully aware that if you follow this process all Adobe Apps will have to be re-installed.

    Here is a link with the instructiions: https://helpx.adobe.com/creative-cloud/apps/troubleshoot/diagnostics-repair-tools/run-creative-cloud-cleaner-tool.html
