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.
Note: Beginning June 14, 2011, Adobe AIR is no longer supported for desktop Linux distributions. Users can install and run AIR 2.6 and earlier applications but will not be able to install or update to AIR 2.7.The last version to support desktop Linux distributions is AIR 2.6. AIR 2.6 is available from the AIR Archive.
Before you begin troubleshooting, perform the following tasks:
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.
However, you can get an older version of Adobe AIR here.
The installation program installs Adobe AIR at the following location for both 32-bit and 64-bit versions of Linux:
- /opt/Adobe AIR
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.
For Adobe AIR 1.0 to 1.5.3, see this document for more information.
You can find the install log at the following location for both 32-bit and 64-bit versions of Linux:
You are seeing this error because Adobe AIR was unable to detect any supported authentication tools on the system. Adobe AIR requires root privileges and can elevate a normal user to root for installation of Adobe AIR and Adobe AIR applications. Such problems arise when you don't have the tools to switch from a normal user to root user. See the following document for more details:
On certain Fedora Core and OpenSuse systems, an AIR application installation can crash. This issue does not occur in AIR 2.0, but the workaround for AIR 1.5.x is to rename the "/etc/opt/Adobe/certificates/crypt" folder:
sudo mv /etc/opt/Adobe/certificates/crypt /etc/opt/Adobe/certificates/crypt_bak
Problem with badge installation
For badge installation of an Adobe AIR application, sometimes developers set the WMode attribute as "transparent" or "opaque" (windowless modes) in the HTML embed tag. Using these attributes result in badge installation problems on Linux platforms. Also, it sometimes leads to "Error #2044: Unhandled ErrorEvent:. text=Error #2074: The stage is too small to fit the download ui." The following document details steps for Adobe AIR application developers to correct the issue:
Adobe AIR applications on Linux are sometimes not able to access the Encrypted Local Storage (ELS) keystore. This issue results in the Adobe AIR application displaying behaviors such as hanging or displaying an empty window on launch.Or, it's possible that the save password feature doesn't work. This document details some of the frequent problems encountered while using ELS and steps to solve them whenever possible:
64-bit issue. "package architecture (i386) does not match system (amd64)"
On Ubuntu 64-bit OS, when you try to install the AIR Debian package, you receive this error. To proceed with the installation, run the following command:
$ sudo dpkg -i --force-architecture adobeair.deb
64-bit binaries of Adobe AIR are currently not available. Running 32-bit Adobe AIR on 64-bit systems has not been fully tested. However, Adobe expects 32-bit Adobe AIR to run on its supported distributions (Fedora Core 11, Ubuntu 9.04 and OpenSuSe 11.1). (It's necessary that the required 32-bit libraries and packages are installed.) See the following document for more details:
