AIR 30 incompatible with Windows XP

I just tested AIR 29.0 vs AIR 30.0 captiva runtime on Windows XP.

AIR 29.0 works and AIR 30.0 (not compiled as 64 bits) gave me the following error message: "... is not a valid Win32 application".

I know that Windows XP is dated and there is no more support from Microsoft, however there is a lot of Windows XP machines out there.

It's not the end of the world because my updater mechanism was prepared for this.

I can provide a x86 version with AIR 29 as final (the very last one) and AIR 30 for x64.
