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.
| Version | Uninstall? |
|---|---|
| Alpha | Uninstall |
| Beta 1 | Will be uninstalled automatically by the Adobe AIR 1.0 installer |
| Beta 2 | No need to uninstall |
| Beta 3 | No 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.
To uninstall all prerelease versions of Adobe AIR on Windows, follow these steps:
In the Windows Start menu, select Settings
Control
Panel.
Select the Add or Remove Programs control panel.
Click the Change/Remove button.
Follow these steps to uninstall all prerelease versions of Adobe AIR on the Mac. Depending on the prerelease version(s) of Adobe AIR that you have installed, all steps may not apply.
Delete the /Library/Frameworks/Adobe Apollo.framework directory.
Delete the /Library/Receipts/Adobe Apollo.pkg file.
Empty the Trash.
Once you have done this, you are ready to install the 1.0 runtime.
