Problem with installing Photoshop CS3

When you want to install Photoshop CS3 (either download trial version from their website or you buy a pi**ted CD/DVD), you might face this problem:

"Please insert Photoshop CS3 to continue installation"

This stupid problem takes me more than 3 hours to solve it. Again, I find countless useful tips in Google to solve my problem. After Google-ing, I found that many Photoshop users facing this problem when they tried to install it. Thank you for online users provide few methods to solve this problem such as:

• Uninstall completely previous photoshop (any single files in your drive including registry need to be deleted)
• Copy the entire file from CD/DVD, and try to instal from your harddisc.
• Reinstall/Format your windows (YES, you have to reinstall your windows! This is ridiculous; I will only try if I can’t find any other better option. Obviously, I didn’t choose this option, if not another 2 hours to solve this problem,haha)
• Create an image CD/DVD file or make a copy of CD/DVD. Beware of the directory structure and name of the CD/DVD. For this, you have to check the setup.xml file resides in the folder called ‘payloads’, open the file with notepad and find the entries like:
  "Payload folder="AdobeALMAnchorServiceAll">Adobe CS3<" The words in bold where in my case is ‘Adobe CS3’ is the master folder name for your image CD/DVD file.

After few hours, I found that last option tend to fix my problem. Goshh, it wasted so much time just to install this bloody photoshop.
