Adobe AIR is a computer program known as a runtime. It is necessary to have Adobe AIR on your computer to run certain applications. Applications that require Adobe AIR are called Adobe AIR applications.

Most Adobe AIR problems are related to having the correct version of Adobe AIR. Before you begin troubleshooting your problem, get the latest version of Adobe AIR for your operating system. Adobe AIR is available for free.

Before you begin troubleshooting, perform the following tasks:

Determine the version of Adobe AIR on your computer

Adobe AIR SDK & Compiler (version for Win & Mac) Adobe® AIR® SDK & Compiler ( Release Notes ) provides developers with a consistent and flexible development environment for the delivery of out-of-browser applications and games across devices and platforms (Windows, Mac, iOS, Android).

An Adobe AIR application requires a minimum version of Adobe AIR. Typically, the Adobe AIR application's installation program makes sure that your computer has the correct version of Adobe AIR. If necessary, the Adobe AIR application downloads and installs the latest version of Adobe AIR.

You can check which version of Adobe AIR is installed on your computer. To do so, follow the steps provided here.

The Adobe AIR installation log file can help you troubleshoot your installation problem. You can also use the log's contents if you post a question to the Adobe AIR installation issues forum.

The application could not be installed because the AIR file is damaged. Try obtaining a new AIR file from the application author.

The .airappinstall.log file can reveal the specific issue. The Adobe AIR application installer could've found an instance of Adobe AIR or the Adobe AIR application on a mounted drive other than main drive. Time Machine (10.5.x) could have a backup of the application. Unmount drives other than main drive and retry installation.

It's possible that the Adobe AIR application didn't download from the website completely. Retry downloading the Adobe AIR application (the .air file).

You could receive an invalid signature verification log error if the certificate used to sign the Adobe AIR application has expired.

The user interface / window does not appear when running an Adobe AIR application, the Adobe AIR installer, or the Adobe AIR uninstaller.

Check the locale settings to see if Latin American Spanish (es-419) is in the list. Incorrect settings trigger an esoteric bug that can cause the behavior described in the Adobe AIR installer and uninstaller, and in some Adobe AIR applications.

The Adobe AIR installer doesn't display a window when launched.
