# Alternative Installation Instructions (PC)

I sent you to this page because you're trying to install XLKitLearn on a computer that is locked down in some way by your company. Unfortunately, these situations are not supported by default - it's super difficult to design an add-in that can be installed without at least basic permissions!

Nevertheless, I've written this page with potential solutions that might work for you, based on the experiences of hundreds of students in the past.

• Getting around installing the .exe file
• Additional step for McKinsey computers
• If all else fails

# Getting around installing the .exe file

If you are having trouble installing the .exe file in the first step of the add-in installation instructions, try this.

• Go to the start menu, search for for cmd and open a command prompt. Type echo %LOCALAPPDATA% and press enter. The terminal will print out a path (in my case in the screenshot below, it was C:\Users\crg2133\AppData\Local). Copy this folder path somewhere.

• Download this zip file. When you open it, you should find a single folder in there called XLKitLearn. Unzip this folder directly into the path you copied above. This unzipping process might take 20 minutes or so - there are a lot of files to unzip!

• You should end up with a folder called XLKitLearn in the folder you copied above. This folder should have a file called python3.exe.

• You are now in the same position as you would be if you had installed the .exe file in the the first step of the add-in. Proceed as in the instructions.

# If your computer is from McKinsey

If your computer is from McKinsey, you also need to carry out the following steps once you have installed the .exe (or carried out the steps above):

1. Download the XLKitLearn.xlsm file, as instructed in the installation instructions

2. Call GHD so they can run the following code on their command window with Admin Rights

Powershell

cd C:\Temp.\Defender_ASR_Exception.ps1

3. Run the Defender_ASR_Exception.ps1 file, and type in your McKinsey password

5. Right click on the XLKitLearn.xlsm file, and click on Add to Windows Defender Exclusions
