I am in the procces of completing this...
Step 1: First you want to download and install the Adobe Photoshop CS5 Extended trial from the Adobe website. (You're going to need a free account.) URL:
https://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 File attached to this topic and place it on your Desktop
[YOU MUST BE REGISTERED TO DOWNLOAD THIS FILE]Step 4: Inside the archive there's a file titled "hosts". Extract this file to your desktop, then drag it to the above directory (drivers\etc). It should ask if you want to overwrite or replace the file. CLick "Yes" or "ok".
Note: If you have trouble overwriting, take ownership of your original "hosts" file then try replacing it again. Google this: "how to take ownership of a file".
Step 5: 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
Congradulations! You have just installed and cracked Adobe Photoshop CS5
