I don’t even work in IT but I make complex Excel tools for my Finance team.
I get an email about once every week or two from one of my coworkers asking what to do about an issue. Nearly every single issue would have been resolved if they just read even the first few instructions.
My favorite is a specific tool we use to review the financials. It relies on Scripting.Dictionary which is only present in .NET 3.5.1 or prior. The very first instruction on the file says you need to download it. There’s even a very handy button right there which will take you to our software center to install it.
Yet every single time someone gets a new laptop, they immediately assume that the file is broken.
