Failed installation AIR on Fedora 15

Greetings,

I am trying to install the Air 2.6 (AdobeAIRInstaller.bin) on a Fedora 15, but failed. The installation log is as following.

[setup:15962][ERR] Runtime Installer end with exit code 7

I tried the -slient option

sudo ./AdobeAIRInstaller.bin -silent

Adobe AIR is currently not installed

Installing version 2.6.0.19170

failed (consult log)

Could you please help in on this issue? Thanks!
