Did you figure it out? One of my clients is reporting the same issue. It works for a lot of other people though.

I think its to do with the path it saves to. I do not have access to my CU computer that experiences the issue so I got the info manually.
If it helps and you have access to a computer that you can test on, change the destination where it writes and remove the variable " & UserName & " to a permanent one. My guess is something with this variable is making an issue.

Regarding the error code 800A004C:

The error can occur if you've relocated the Desktop folder or your Users home path is in a different drive than C:.

Change the following code in line #60:

fName = "C:\Users\" & UserName & "\Desktop\WindowsKeyInfo.txt"

to a fixed path like:

fName = "D:\WindowsKeyInfo.txt"
