Download for a x64-based PC . every time i try to update it tells me i need either a (x86)bit or (64)bit . my system is 64

Sounds like you are attempting to install the 64 bit version on a 32 bit PC. You will need a 32 bit install disk.

right click on my computer or computer on the start menu and click on properties. then from there it should tell you weather your computer is x86 or x64 x86=32 bit and x64= 64bit

Make sure you downloaded the correct drivers for your operating system. Check if you OS is 64 or 32 bit, you can follow these steps to do that: http://windows.microsoft.com/en-CA/windows7/find-out-32-or-64-bit
If your operating system is 64 bit or x64 you can use the 64 bit or x64 installer, otherwise download the 32 bit or x86 driver.

If that didn't fix your problem, try right clicking the installer and click Properties>"Compatibility" tab> select "Run Program as Administrator"

Make sure that your system is running Service Pack 1 before you install Service Pack 2.

Hello your computers homepage is here.

Yes there is a way to upgrade (i guees you mean the sevice pack)

You can download the sp1 here:

http://www.microsoft.com/en-us/download/details.aspx?id=5842

But you have to know if your system is 32 or 64 bit.

If your system is 64 bit:

Download this file.

windows6.1-KB976932-X64.exe

And the 32 bit:

windows6.1-KB976932-X86.exe

When downloaded run the exe program

Then you forceing it to install the sevice pack.

A firewall/antivirus could be blocking so you can`t update the service pack. Try to set it off while you install sp1.
Remember to set it on again when the job is done.

Your Pc haves to restart many times after this.

Good luck

You need to check the specifications of your laptop it may not be able to run Windows 7.
You need these specs:

• 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  

• 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
  

• 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  

• DirectX 9 graphics device with WDDM 1.0 or higher driver
  

Generally - you simply need to right-click anywhere on the desktop that does not have an icon present, and select "Screen resolution". Adjust the slider as needed to obtain the desired resolution. If the resolution desired is not available, choose another that is close.

Digging deeper, you might want to investigate the "Advanced settings" to make sure that you've got the correct drivers loaded in the settings for both the "Adapter" and "Monitor" tabs.

Lastly, "Windows Ultimate x64" is the 64 bit version of Windows. The 32-bit version is referred to as "Windows Ultimate x86" If there are both 32-bit and 64-bit drivers available for your Aspire, make sure you get the correct version 32-bit = x86 and 64-bit = x64. The "x86" tag came from the Intel processor line up where the "x" represented the generation (8, 16 and 32 bit CPUs) and the "86" were the last two digits to indicate the instruction set used by the CPU like this:

8086, 80286, 80386, 80486, etc.

The 64 bit CPUs are not x86 family processors, so they do not carry the x86 tag. Please rate this reply if it was helpful to you - good luck!

Hi buddy323,

You will find the 32 bit browser on your Vista installation disk. Or your restore CD from Dell.

If you can't find it there, you can download it HERE. Or may want to go for the IE version 8.

Good Luck and don't forget to leave a rating.

Thanks Mark
