The .air installer file of my application is damaged.

Hi all,

I am a developer for a desktop application to be installed in windows and mac. The air file is signed and migrated to new certificated as detailed here (Adobe AIR 1.5 * Signing an AIR file to change the application certificate). But while launching the installer in windows, the installer fails with the message "The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author." I have tried doing the following

- checked my date/time

- uninstalled/reinstalled the application

- removed the installtion folder  etc.

But still the issue persists. Before failing, it also shows a dialogue that the "publisher identity is verified" - so I believe this issue is not related with codesigning/certificates, please correct me if I'm wrong.

Please let me know how to resolve this issue.

Thanks,

VivekS
