The five most common contributing factors are:

- Outdated Software: If you’re working with an old version of Adobe After Effects, it might not function smoothly with your computer’s software setup.

How to Help Resolve Adobe After Effects Not Opening
Now that you’re across some of the reasons behind the issue, it’s time to roll up your sleeves and get to fixing it.
There are eight different solutions you can try. Follow these step-by-step instructions and you’ll be back to designing in no time.
1. Update Adobe After Effects
The first step is to ensure you’re running with the latest version of the program. Adobe software updates fix problems like startup issues. They also enhance the usability of the platform overall with added new features. Here’s how to check for updates:
- Launch Adobe Creative Cloud.
- Locate Adobe After Effects in the app list.
- If there’s an update available for After Effects, a button will say Update.

If you’re running the latest version, the bar will read Up to Date and the button Open.

2. Reset Preferences
Issues with your preference choices can sometimes prevent After Effects from opening. But it’s easy to reset your preferences, simply:
- Close After Effects if it’s running.
- Hold down the Ctrl + Alt + Shift keys on your keyboard for Windows and Command + Option + Shift on Mac.
- Launch After Effects while holding the keys.
- A dialogue box will appear, select Reset Preferences.

3. Check Third-Party Plugins
Old and new plugins can both play a part in causing a faulty After Effects. The issue is usually a result of incompatibility between the version of the plugin and the version After Effects. Or, it’s because the plugin has become corrupted.
You can find out if your plugins are behind the issue by following these steps:
- Go to the After Effects folder on your computer (usually in the Applications folder).
- Locate the Plug-ins folder.
- Temporarily move all third-party plugins out of this folder to a different location (e.g., a desktop folder).
- Try launching After Effects. If it opens, one of the plugins may be causing the problem. Reinstall or update them one by one to single out the culprit.

4. Review the Necessary Computer Requirements
Adobe asks that your computer meets certain requirements for things like the processor, storage, or graphics card. Meeting these requirements ensures smooth running. It’s a good idea to check to see if your machine meets the minimum specifications, some of these include:
- A 64-bit processor and operating system (Microsoft Windows 10 (64-bit) V20H2 or later – and macOS Big Sur v11.0 or later).
- At least 16 GB of RAM (32 GB or more recommended).
- 2 GB of dedicated GPU (Graphics Processing Unit).
- Sufficient free storage space on your hard drive, minimum 15 GB with 64 GB recommended.
If your computer falls short in any of these aspects, it might be time to consider an upgrade. Here’s how to check what specifications you’re currently running with:
- Windows: Click the Windows button, then Settings. In the menu, select System. Scroll down and hit About.
- macOS: Choose the Apple menu, then System Settings. Select General in the sidebar and About on the right.

5. Disable Conflicting Software
Sometimes, background processes from other software can interfere with how After Effects runs. To troubleshoot this, simply:
- Close all unnecessary background applications.
- Disable or uninstall any recently installed software that might conflict with After Effects.
- Restart your computer and try launching After Effects again.
6. Reinstall Adobe After Effects
If none of the above solutions work, you may need to hit refresh on the program altogether. To reinstall After Effects, you can:
- Uninstall Adobe After Effects from your computer.
- Download the latest version from the official Adobe website.
- Install the software and launch it.
Tip: Make sure you have your Adobe Creative Cloud credentials ready for activation.

7. Check for System Updates

Here’s the best way to check for updates:
- Windows: Click the Windows button, then Settings. In the menu, select Update & Security and Windows Update. Check for updates and install.
