Adobe AIR installation fails on Fedora 10 x86_64 without any explanations. It just says:

An error occurred while installing Adobe AIR. Installation may not be allowed by your administrator. Please contact your administrator.

The reason is some missing i386 packages. You just have to run following command:

yum install gtk2-devel.i386 nss.i386 libxml2-devel.i386 libxslt.i386 gnome-keyring.i386 rpm-devel.i386

You may already have some these packages. Don’t worry about that, yum will skip them. After yum finishes, retry installation of AIR, it should work now.

I’ve just discovered that when intalling Fedora 10 on some computer causes this problem. Problem start from instalation: there is no pointer for mouse in Anaconda and further in the system. It is a little bit dificult but install system with keaboard only, then when system installed and running do the following steps to fix this issue:

# yum install system-config-display

Open system-config-display and just press “OK” button. It will generate xorg.conf file in /etc/X11.
Then open /etc/X11/xorg.conf and in section “Device” add following two lines

Option     "HWCursor"     "off"
Option     "SWcursor"     "True"

Save file and restart your X server. It have to work now.
