AIR ADL invalid application descriptor

Hi, everyone.

I have problem with running AIR aplications when installed Ruby under Windows 7.

If I try to run adl for my program "adl application.xml bin", I get the next result:

C:\Documents and Settings\User\Desktop\New Project>adl application.xml bin

NOTE: Gem.cache is deprecated, use Gem::source_index. It will be removed on or after 2011-08-01.

Gem.cache called from C:/Ruby192/lib/ruby/gems/1.9.1/gems/sprout-0.7.246/lib/sprout.rb:365

.

invalid application descriptor: Unknown namespace: http://ns.adobe.com/air/application/3.7

C:\Documents and Settings\User\Desktop\New Project>

Similar problem on the two different computers.

When I uninstalled Ruby AIR applications  worked normally.

But I need Ruby and I need AIR.

When I type just "adl" in command promt, I get result:

Adobe (R) AIR (R) Debug Launcher (ADL)
