An Adobe After Effects Project File is used for storing project related data. The AAE file extension uses AES encryption to protect the file contents against unauthorized access. Only users with the correct password will be able to open files that are protected using AES standard encryption. Typically, an AAE file stores video and audio assets along with other additional information required by Adobe After Effects.

To open an AAE file on a Windows computer, you will need to have the Adobe After Effects software installed on your system. If you do not have this software installed, you can download it from the Adobe website. Once the software is installed, open the application and select “Open” from the File menu. From the file browser window that opens, navigate to the location on your computer where the AAE file is saved and double-click it.

Windows should be able to automatically identify the software installed on your computer that is associated with an AAE file and open it using Adobe After Effects. If you experience problems selecting an AAE file in Windows, you may need to change your Windows registry settings. To do so, open the “Run” command prompt by simultaneously pressing the “Windows” and “R” keys on your keyboard. Type in “regedit” in the box that opens up and hit enter. This will launch the Registry Editor in Windows where you can navigate to the following key:

HKEY_CLASSES_ROOT\aaefile\shell\open\command

In the right-pane, double-click on ” (default)” and change its value to:

“C:\Program Files\Adobe\Adobe After Effects CS5.5\Support Files\AfterFX.exe” “%1”

Close the Registry Editor and try to open an AAE file on Windows again. If you are still unable to do so, there may be a possibility that your AAE files are configured for viewing only (read-only), preventing Windows from opening them with any software application installed on your computer. To change this setting, right-click on the AAE file and select “Properties” from the menu. Under the “General” tab, uncheck the box next to “Read-only” and click on “OK”.

Now you should be able to open an AAE file using Adobe After Effects or any other software application that is installed on your computer. However, if you are still unable to do so, you may need to check your Windows registry for any errors caused by improper registry editing or file associations. To fix this, I recommend using RegServe (download link here). It is a free software which can help you correct invalid registry entries and restore default application associations with the AAE file extension. To use the software, follow these steps:

Step 1 – Launch RegServe and click on “Repair” to run a free diagnostic scan for invalid registry entries and file associations.

Step 2 – If any errors are detected, register your copy of RegServe by clicking on the button below and following the instructions given:

Step 3 – Once you have bought the software, click on “Register” to open up a registration window. Enter your name and email address and click on “Register”.

You should now be able to open an AAE file using Adobe After Effects or any other software that is configured as the default program for this file type. If you continue experiencing problems, please contact our support team for assistance.
