Description
A Tool to modify Compiled Papyrus Scripts (.PEX) files
Works for both Fallout 4 and Skyrim. 

Warning:
This tool is still in alpha and may contain a lot of unknown bugs so use with caution.
All scripts that you save will automatically have a backup created, so in worst case scenario you can just revert back.

Pex Files to modify?
I have included a "pexlibrary.zip" with this package that includes all Fallout 4 .PEX files available.
Unzip this one and you should be ready to start modding! 

Installing
There are nothing special, after unzipping the package you should be able to run it by starting PexInspector.bat or the 
PapyrusDotNet.PexInspector.exe that exists inside the /bin/ folder.
PexInspector requires .NET Framework 4.5.2 to be installed. If you do not have it installed already, you can download it here https://www.microsoft.com/en-us/download/details.aspx?id=42642
