2.2. Uninstalling Prerelease Versions of Adobe AIR

If you have installed prerelease (alpha and/or beta) versions of Adobe AIR, you may need to uninstall them before installing the 1.0 runtime. However, whether this is strictly required can be a little tricky to determine.

Table 2-1 lists the prerelease versions of Adobe AIR and whether they should be uninstalled before installing Adobe AIR 1.0.

Table 2-1. Prerelease versions of Adobe AIR
VersionUninstall?
AlphaUninstall
Beta 1Will be uninstalled automatically by the Adobe AIR 1.0 installer
Beta 2No need to uninstall
Beta 3No need to uninstall


As Table 2-1 shows, the beta 2 and beta 3 runtimes can run side by side with Adobe AIR 1.0. This allows you to run applications built for beta 2 and beta 3 until those betas expire.

If you do not know whether you have installed the alpha version, it is a good idea to go ahead and uninstall all prerelease versions of Adobe AIR.
