I have Corel art dabbler on pc running XP home. When I try to load it on laptop running Vista get message-not enough memory. As I have 4Gb this must be an error.

I dont think there's such a thing as "too much".

Start "Help" within Vista.
Search for "Compatibility Wizard".
Launch this wizard.
Tell it that you have a "Windows XP" application that you want to install.
Point the wizard to the CD-ROM containing the software.
Install the software.

Now, when the software runs, Vista will create a "virtual XP" system, that will run the XP-only software.

this is common to Hp. your graphics card is not enough for playing high graphics game.

If yours is a PC, Windows Vsita 64 bit should recognize 4 GB RAM. Have you tried the 64 bit bootable linux? Try with that. If you see less than 4GB, then you must check your BIOS for some setting which is the setting to share to the graphics memory or some limit.

go for the nvidia geforce 8500, your board Support for up to 2 GB of system memory so no 4GB( too bad)

Verify the setting via Manage accounts on your XP machine (the one the email client works on) in whatever email client you use on it and verify and edit if need be the setting in your Windows Live Mail on your Vista home Laptop.

I had the same problem! Later found that my USB cable was broken! Try another USB cable.

The maximum amount of memory that your system can use is actually limited in two ways — not only is there a maximum amount of memory that your computer motherboard can accept, there is also a maximum amount of memory that your operating system (OS) can accept.

For instance, when you install 4GB of memory in a 32-bit Windows system (the most common version; 64-bit systems are typically used only by high-end users), your system will see (and utilize) only 3GB or 3.5GB.
Relax, there isn't a problem with the memory. Windows allows for 4GB of memory to be addressed, but this isn't 100 percent the same as having 4GB of physical memory.

What happens is that some of the addressable memory (regardless of how much you have physically installed) is reserved for use by page files or by some of the devices that you are using, such as a graphics card, PCI card, integrated network connections, etc., so it's unavailable for use as normal main memory.

The amount of memory needed for these devices is calculated by your system at startup; if you haven't maxed out the memory in your system, it's invisible to you, and all your physical memory (the RAM that's installed) is available for use. However if you've maxed out the DRAM in your system, this amount will be deducted from your physical memory, so you can't use 100% of your DRAM.

The maximum memory limitation varies by operating system; for instance, the 4GB memory limitation doesn't exist in 64-bit versions of Windows.

Memory maximums for current Microsoft® Windows OSs include:

• Windows XP Home: 4GB
  
• Windows XP Professional: 4GB
  
• Windows XP 32-bit: 4GB
  
• Windows XP 64-bit: 128GB
  
• Windows Vista Home Basic: 4GB
  
• Windows Vista Home Basic 64-bit: 8GB
  
• Windows Vista Home Premium: 4GB
  
• Windows Vista Home Premium 64-bit: 16GB
  
• Windows Vista Ultimate: 4GB
  
• Windows Vista Ultimate 64-bit: 128GB+
  
• Windows Vista 32-bit: 4GB
  
• Windows Vista 64-bit: 128GB+
  

try to run again the system restore cd, what OS you are using? is it old or new acer laptop?
if you have new laptop with Vista OS it should be ok.
if you have new laptop design for vista but rather installed XP maybe you will encounter difficulties loading drivers if you dont have xp driver cd (acer provided)
if you have old laptop with XP OS it should be ok.
if you have old laptop w/ lower memory and trying to install Vista it will not work or you will incounter difficulties

System Requirements:

Processor:
# Pentium III, 800MHz or AMD Athlon XP

Operating System:
# Windows XP with Service Pack 2 or later
# Windows Vista (32-bit or 64-bit editions)

Hard Disk:
# 430 MB

Memory:
# 512 MB RAM

Optical Drive:
# DVD-ROM

Other:
# 1,024 × 768 or better monitor resolution
# Mouse or tablet

Where these are the minimum specs I would recommend at least 1+gb memory and a good graphics card and a P4 or AMD processor running at 1.8ghz or better, and that would depend on how in depth you get into the program
