Follow the below steps
Step 1: First you need to download and install
the Adobe Photoshop CS5 Extended
Trial from the Adobe website. (You're
going to need a free account.)
URL: http://www.adobe.com/cfusion/tdrc/
index.cfm?
product=photoshop&loc=en_us
Step 2: Then once the trial is installed, make
sure Photoshop is closed and navigate
to this directory: C:\WINDOWS\system32\drivers\etc\
Step 3: Download the zip archive given
below . Inside the archive there's a file
titled "hosts". Extract this file to your
desktop, then copy it to the above
directory given in step 2 (drivers\etc).
It should ask if you want to overwrite or replace the file. CLick "Yes" or "ok". If you have trouble overwriting, take
ownership of your original "hosts" file
then try replacing it again. OR Google
this: "how to take ownership of a file"
Step 4: Almost done. Open Photoshop. There
will be a window asking for a serial
number.
Use one of these:
1330-1036-2793-5476-2605-5729
1330-1193-9982-0310-7670-2199
1330-1470-0441-6829-3063-2553
Now You Are Done
