Installing Programs Blocked by Group Policy on PC Using an Extraction (Unzipping) Program
Posted by Michael Sturm, Last modified by Michael Sturm on 06 October 2015 02:03 PM
Skidmore employs a technique through Group Policy to prevent harmful viruses from installing themselves on campus computers. This helps keep our computers safe from malicious attacks, but these tactics can sometimes prevent legitimate programs from installing. Please read on to learn how to circumvent this to install programs you’ve verified as safe. In our example, we’ll be using a firefox installer to setup the Firefox web browser.
Installing 7-Zip for Extraction
7-Zip is an excellent tool for extracting files and folders, and will be our program of choice in this guide. If you already have another extraction tool installed, such as WinRAR, you can use this as well to achieve the same results.
7-Zip can be downloaded from the official website at: http://www.7-zip.org/
Using 7-Zip to Extract the Installer
Once 7-Zip has been installed, there are two ways to extract your program’s installer file to access the setup utility. The first, and most convenient, is to locate the file in the file explorer, and right click on it to reveal the contextual menu. In this menu, move your move over the “7-Zip” option to display another dropdown:
From here, you can select the extraction option you prefer. “Extract files…” will allow you to choose the location of file extraction. However, you can also simply choose to extract the file to a new folder in the current location of the file, saving time and energy. In our example, choosing the Extract to “Firefox setup 40.0.2\” will do so.
If this option does not appear for you, however, you can open up the 7-Zip File Manager through the start menu by pressing the start button in the lower left hand corner, searching “7-Zip” and clicking on the associated icon as shown below:
From here, you’ll see a list of folders. Navigate to your file, highlight it, and press the “Extract” button indicated by the orange 1. You’ll see a pop-up window appear as indicated below—press the “OK” button as indicated by the orange 2. if you’re satisfied with this location.
Installing the Program Using the Extracted Files
Now, in the location of the original file, you will find another installer, typically named Setup.exe—please run this, and your program should install without being blocked by group policy!
Success! If you have any issues during this process, please feel free to call or stop by the IT Help Desk.
