(adsbygoogle = window.adsbygoogle || []).push({}); Okay first off there are many ways to do this. I will only be listing some and the ones I think are easy.

---------------------------------------------------------
First Way: BootCamp Partition With Windows On It
(THIS IS THE BEST WAY AND MY FAVORITE)
---------------------------------------------------------
Requirements:
* 10 - 20 GB Space Recomended
* A Windows Disc
* A Macintosh Computer
* Boot Camp Assistant

I will have to tell you though you are going to be installing windows on your mac, and this could take up to 40 mins, or if your running a slow mac it could take up to 2 hours.

If you are willing to do this method here is the steps

1. Open Boot Camp Assistant
2. Select Partition Size
3. Put Windows Disc in your Mac
4. Your Mac will now reboot and all you have to do is follow the intructions to install windows.

-After windows is finshed installing then you can download the patchblocker and run it no problems -

-----------------------
Second Way:
-----------------------
If you do not want to go through the long process of installing windows on your mac then you might be considering a program called crossover.

Requirements
*CrossOver
*Some DLL and OCX Files
*Microsoft .Net Framework



*Crossover allows your mac to run windows files via X11 no install of windows needed*

1. Download CrossOver from CodeWeavers.com
2. Once finshed downloading open it up
3. Set up the settings as you wish.
4. You will notice EXE files now turn into the CrossOver logo
5. If Microsoft Net Framework 3.5 not already downloaded and installed on CrossOver then you must download it.
6. Install Required DDL and OCX files for the Patchblocker
7. File>Open, Patchblocker.exe you have downloaded.

------------------------
Third Way:
------------------------
The 3rd way requires you to install windows as well but less time consuming and you can switch from windows to mac without restarting you mac. This program is a Virtual Machines. You can download either virtual machine listed below, your choice.

Requirements:
*A Virtual Machine
*A Windows Disc or Windows ISO
*A Mac Computer

Several Popular Virtual Machines Inlcude:
*Parallels Desktop
*Vmware Fusion

Once you have setup and downloaded a virtual machine you will be asked to install windows...but this process will be faster and you don't need a disc you can just download a .iso file of whatever windows version you like. After you get the windows installed you can immediately download The Unknown's PatchBlocker.

Hope this helped!
+ Rep Would Also Be Appreciated and Nice!

Another way is using Darwine, you can run .EXE files on a Mac with no virtualisation needed. But you may need the DLL files for it.

Yup alot of DLL files.

Depends what program it is But normally for a basic program it's 6 or 7.
