Installing driver from .zip?

I bought a device called PenPower. Somehow, the driver cd is not included Anyway I decided to google for the driver and I found this:

http://www.hclhk.com/software/penpower driver/pJh50.zip

The thing is, it comes in .zip format. I can extract it just fine, but when doing so, there are some files that have the same name and they ask me to overwrite.

So anyway, how do I install the driver from this file? Do I need some kind of tools? Daemon Tools doesnt work btw..

 

-Go to start>control panel and click systems. Go to the hardware tab and click device manager. Look for the device you want to update the driver for and double click it. Go to the driver tab and click on update driver.

-A screen will pop up like in the automatic install. Select "install for a list or specific location" this time and click next. Uncheck "search removable media" and check "include this location in search". Click the browse button and go to the directory where you saved your new driver.

-Click next and it will attempt to install the driver. Once done click next and your new driver is install. A reboot might be required for the device to work properly.
