adobe photoshop cs4 fail to install in my machine

I'm using

1. windows xp sp - 2
2. dual core processor
3. 2 mb ram

Does that mean my configuration doesn't support cs4?

* Intel® Pentium® 4 or AMD Athlon® 64 processor

* 1GB of RAM
* 1GB of available hard-disk space for installation; additional free space required during installation (cannot install on removable flash-based storage devices)
* 1024x768 display (1280x800 recommended) with qualified hardware-accelerated OpenGL graphics card, 16-bit color, and 256MB of VRAM

Your configuration should support CS4, however the system requirements listed here:
http://store.adobe.com/store/en_us/popup/software/photoshop4/systemreqs.html recommend XP with SP3.

Does the failed installation provide an error message?

 

You know that XP-SP2 is no longer a supported OS?

 

There was no error message except that the computer restarts itself when installation reached 90%.

 

Is this a legit copy of the program?

Do you have any other adobe products, such as earlier versions of photoshop installed on your computer?

Go to add/remove programs in the control panel and look for other instances of adobe, which may be presenting a conflict with the new installation.

Another thing to consider would be an upgrade to XP SP3, as SP2 is no longer supported and you are undoubtedly missing out on updates (windows installer, perhaps), which could help your situation.

 

I have uninstalled photoshop 7 which i used earlier but probably i forgot to remove other adobe programs such as adobe reader which may caused the problem.

yes i have installed the latest version of windows installer but my windows xp sp 2 may have caused the main problem.

 

Updating to SP 3 would probably help.
