Adobe Flash Builder gets installed into C:\Program Files\Adobe\Adobe Flash
Builder 4.7 (64 Bit)\ That comes with a 'sdks' folder with 4.6.0 and 3.6.0
pre-installed. Naturally, folks want to add new SDKs into this directory to
keep all the SDKs organized.
The problem is that the C:\Program Files directory is writable only with
Admin access by default.
One way to address this issue is to inform the user that the selected
directory is not writable. I believe this is the fix Neil has submitted.
A more correct way would be to detect the current user's UAC level and
alerting the user that UAC needs to raised to install in the selected
directory. [1]
The best way would be show the windows UAC dialog prompting the user to
allow the write operation. I don't think it is possible with AIR
directly. So, we will need to write a small script and invoke it via a
nativeprocess. The elevated UAC will be valid until the Installer is
closed.
The problem would be if the user does not have the Admin username/password
which they will have to enter to proceed with the installation. If they
don't have it, we should direct them to use a lower privileged directory
such as c:/temp or c:/users/{username}/AppData/Roaming/{FlexInstallationDir}
Of course, we can chose to skip all this by automatically selecting a
default directory such as
c:/Users/{username}/AppData/Roaming/{FlexInstallationDir} This path should
be pretty straightforward to retrieve from the AIR apis.
Thanks,
Om
