32bit, run the program as administrator: "TCPZ_Setup-x86.exe".
64bit, run the program as administrator: "TCPZ_Setup-x64.exe"
If OS prompts driver has not been signed, please accept and continue the installation.
If you already exists the old version of the software, please uninstall it first.
Or you do not use the script to install, you can use "Add Hardware" in "Control Panel".

b. Double-click Add Hardware.
If you are prompted for an administrator password or for confirmation, type the password, or click Continue.
c. Click Next.
d. Click Install the hardware that I manually select from a list (Advanced), and then click Next.
e. When you are prompted "Do you want Windows to search for your new hardware?" click No.
f. Click the hardware type for the driver you are installing, and then click Next.
g. Click Have Disk.
h. point to the folder of the driver file: "Driver\tcpz.inf".
i. Follow the instructions on your screen.
3, After successful installation, you can see a device named "TCPZ Driver" in the device manager.
Open the properties of "TCP Half Open Limited Patcher ( TCP-Z)", and check current limited value. If current value is 252, that means the patcher working perfectly.
This virtual device will run automatically when Windows starts, and modify TCP half open limited value to 252, or more.

why is it not possible to go more than 252 under the memory limit in Vista?
Tcpip.sys of Vista/Windows 7, there are only 1 byte for comparing, so the maximum is 0xFF (255).

Ahhh I got it working with the virtual driver! Thanks a lot man!! My tcpz64.exe shows the memory limit after I applied the virtual driver as 252. I am not a programmer but tell me why is it not possible to go more than 252 under the memory limit in Vista?
