Upgrade from Mac Os X Leopard to Snow Leopard

Hi,
I've got a problem I'm not able to fix out. After launching the installation application, there's written: "Mac OS X cannot be installed on this computer." I've tried to find solutions to this problem but I was not successful. Partition table of my disc is Guid.
Could you please help me?

As a brody says, 14 GB free is not a good idea, but Snow Leopard should install.
It's possible there's something corrupted on your startup volume. Try Verifying it, per #6 in [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html] (or use the link in *User Tips* at the top of the +Using Snow Leopard+ forum).

If your Mac meets the System Requirements for Snow Leopard you do not need leopard.
Snow Leopard = OS X 10.6.x
It is Not available as a download... It is a Paid Upgrade.
Do this first...
Check that your Mac meets the System Requirements for Snow Leopard...

After the Successful Install, run Software Update to get the latest updates for Snow Leopard.

Yes

Will upgrading from Tiger 10.4.11 to Snow Leopard delete programs?

Sorry if this is a stupid question or answered a million times before, but will upgrading from Tiger 10.4.11 to Snow Leopard stop my existing programs (PhotoShop, Office etc) from running? I've got an Intel MacBook but I've never installed a new OS myself, so any tips gratefully received! Thank you.

You will lose the ability to work in any Classic OS applications that ran under system 9.
If I were you, before upgrading do yourself a favor and purchase an external hard drive that you can "clone" your Mac to. If possible, a large enough drive that you can have 2 partitions. In one you would clone your current system and apps. Then after the upgrade, clone again your updated system to the other partition as a emergency backup.
With the clone of your current set up, if need be you can rebbot to it so that you can use any of your "old" applications.

Upgrading from OS 10.4.11 to Snow Leopard

Hello, I've heard mixed reviews from people at the Apple store to people on the street whether it's possible to upgrade directly from 10.4.11 to Snow Leopard. Below are my specs, and I'd love to hear a second opinion from someone!
Model Name: Mac Pro
Model Identifier: MacPro1,1
Processor Name: Dual-Core Intel Xeon
Processor Speed: 3 GHz
Number Of Processors: 2
Total Number Of Cores: 4
L2 Cache (per processor): 4 MB
Memory: 2 GB
Bus Speed: 1.33 GHz
Boot ROM Version: MP11.005C.B08
SMC Version: 1.7f10

You should be able to upgrade the OS X to Snow Leopard with the less costly upgrade DVD
from Apple; that won't give you the newer iLife, or iWorks, but it would be a full install disc.
The computer should see an upgrade in RAM, too; 2GB probably is minimal, and this can be
a concern if you also have a jam-packed hard disk drive and no working free space for the
system or applications to use the OS X's automatic Virtual Memory, based on available space.
An upgrade from Tiger 10.4.11 to Snow Leopard will invite issues and problems from third-party
applications not written to run in the later OS X version; you may have to buy/upgrade them, too.

Anyway, the upgrade by itself on a new or 'secure erased' HDD may work just fine.
The hardware upgrade suggested (RAM, larger hard disk drive) would help. Also,
if there are any pending Firmware updates available, be sure to install them, too.
Good luck & happy computing!

Upgrade from Mac OS X Server 10.5.8 to Snow Leopoard

I need to know how to Upgrade from Mac OS X Server 10.5.8 to Snow Leopoard. I just need to get the 29.00 Snow Leopard? no the 499$. just one server and no clients to him.
thanks

You cannot use the standard desktop Snow Leopard upgrade on a machine running any flavor of OS X Server. There is a lot of 'under-the-hood' functionality that would not take well to attempting this and could render you with a dead Mac until you reinstall the original OS.
If you wish to keep the Server functionality, the Snow Leopard Server upgrade ($499) is the only option.
If you wish to ditch the Server functionality and use the standard desktop version, you would need a copy of the desktop version of OS X 10.5 Leopard and the ($29) Snow Leopard upgrade. Apple does sell both 10.5 and the Snow Leopard upgrade in a combo bundle.

If I upgrade from 10.5.8 (Leopard) to 10.6.5 (Snow Leopard) will I have to reinstall all of my applications? Along with that, will it update all of my applications?

If I upgrade from 10.5.8 (Leopard) to 10.6.5 (Snow Leopard) will I have to reinstall all of my applications? Along with that, will it update all of my applications?

You can upgrade 10.6 right over 10.5 with hardly any issues.
You will not have to resintall any applications, and the only applicaitons that get updates are the bundled one's Apple includes. Not your third party ones, those require your manual updates, but likely not paid updates for the most part.
10.6 is for Intel processors, offeres video card driver improvements, some new UI tweaks and strips out the PPC processor code your not using.
Your sort of already using Snow Leopard already under Leopard, as Leopard is for both Intel and PPC processors.
Now if your thinking of updating to 10.6 to get to 10.7, then yes, your older programs from Leopard and even some from Snow Leopard will not work in Lion 10.7
So 10.6 is as far as you go.

Leopard requirements/10.5.x...
    * Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
minimum system requirements

    * DVD drive for installation
    * 9GB of available disk space (I say 30GB at least)
Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...
