I've installed Leopard in my PC with Vista and dual boot.
All works fine till I decide to search and download updates for the leopard.
After Install and reboot the system, the leopard don't boots.
Does anyone knows if there is a problem installing updates?
Another question, I've installed Adobe Creative Suite for Mac and the programs don't runs.

Regards,

Ok first of all, if you install Leopard to a PC, it's patched. This means a retail updte will kill patchs and render your osx unusable.
Second thing is a common issue with flex licensing looking for a primary interface it cannot find, google for a solution or maybe you can even find it via forum search

The 'Official' 10.5.2 update wont work...atall..dont even try.

You need to download the 300mb or so Kalyway 10.5.2 combo update package from somewhere like the pirate bay (intel version-depending on your system etc..) This does involve a complete re-install of your system.
