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
Cjdsys
