U need a "Computer for dummies" book
lol, corny... anyway.
Lets try this again.
Take a piece of paper, and write down the address of the folder that adobe installer (the setup file that u clicked) resides in.
Then, write down the name of the file u clicked to open the installer.
Then, restart your windows (i am just trying to make things easier for you)
Open "My Computer", then in the address bar, type in the address you wrote down on your paper, and press 'Enter' on your keyboard.
Then, once the folder opens, double-click the file that starts the setup, and run through the installation. Try to leave all the fields the way they are, unless you know what you are doing.
After the install is complete, it may prompt you to restart the computer.
Do so.
NOTE: You might want to write down the insallation address of where you installed Adobe photoshop (u will be prompted to edit it during the installation), but most likely it will be "C:\Program Files\Adobe\Photoshop 6.0" but it could be somewhat different. Just look for a similar string.
After you restart, locate the address from which you ran the set up, and delete it (save space) or write it on a CD if u wish to save it) and then delete it.
Now, you are ready to start drawing.
Have fun.
