Migration Signature Validation Failed

Hi, I am getting an invalid migration signature error when trying to install AIR Launchpad beta 3.0.1.

The machine is running XP SP3, with all patches applied. I have tried switching off antivirus for both download and installation, but with no success.

This is a 'clean' machine, with disk formatted, and OS and all other software re-installed less than a week ago. System time and date are correct.

AIR was installed automatically as part of Flashbuilder 4.5 installation and the update to + 4.5.1 immediately applied.

I have search the net for solutions to this, but found relatively few others with this exact issue. I did find many reports of issues with 'Package' validation errors, whhic are often attributed to certificate failures due to system date/time which I have already checked.

Hope that sombody has an answer.

The log file is attached below.

Many Thanks

Hmmm.

Looked at the system requirements for Launchpad 3.0.1.. Flashbuilder 4.5.1 or 4.5 sdk with AIR 2.6 overlay.. Log showed I was running 2.5.xxxx.

Launched Flashbuilder and searched for updates.. Tells me all versions of Flash Player and AIR are up to date. Decide to try installing another AIR app, so go for Tour De Flex as I want to study the mobile stuff anyway. Installs fine, and on launch, I am immediately offered an AIR update to 2.7.x. Accept the update and low and behold, AIR Launchpad now installs.

Sweet, but wtf?

So, for anyone out there who comes falls foul of this in the future, do not rely on Flashbuilder to confirm your version of AIR is up to date, launch an AIR app instead and you will get the true picture.

Hope this helps some other confused soul.

Thanks for the update, that wasn't a very helpful error when the solution was to update the AIR runtime.  I've asked our cert/installer experts to see if they've seen this before.
