AutoHotkey to use clipboard info to open files in Word works in Win8 but not in Win7 - macros

Question

I created an AHK macro for a colleague. I have Windows 8; she has Windows 7. She has two "pending work" folders, one for documents and the other for audio files. The (text) file names in the documents folder correspond to the file names in the audio folder. So, for example, if there is an audio file called abc123.mp3 in the audio folder, there will be a file named abc123.txt in the documents folder.
As she opens the audio file in her transcription (media player) app, as part of that process, I want to have an AHK macro automatically open the matching text file (in Word).
I created an AHK macro that picks up from the point of her selecting the file to open from her transcription app. At the point where she selects the file, she invokes the AHK shortcut, which then toggles the rename feature (F2), copies the text to the clipboard (Ctrl+C), opens the file (Alt+O), and then uses the clipboard info (along with path info) to open the appropriate text file in Word.
It's working PERFECTLY on my system. However, when I logged into her system earlier today to demo the macros, the macro would not work. It works to a point - it will rename the file, copy the name of the file, and open the audio file, and file name is in the clipboard. But that's where it dies, with no error message. During troubleshooting, I tried isolating the macro down to one command - to simply open (fixed name) file in WinWord.exe, but that doesn't work, either.
I have been unable to find any research related to this issue. I know there are numerous ways to accomplish this task, but my AHK scripting skills and my free time are limited, so I went with what I knew I could accomplish quickly. I am open to suggestions for how to troubleshoot or tweak this macro to get it working on her system. It's hard to troubleshoot when it works on mine!
NumpadEnter::
Send {F2}{Sleep 100}
Clipboard=
Send ^c
Send {Sleep 100}!o{Sleep 100}
Run, WinWord.exe "C:\DocFiles\"%Clipboard%.txt
Return

Just a guess, but I believe you wanted Sleep command and not a Sleep Key? Be sure that you are using the Latest Version of AutoHotkey you can download it from www.ahkscript.org
NumpadEnter::
Send {F2}
Sleep, 100
Clipboard=
Send, ^c
Run, WinWord.exe "C:\DocFiles\"%Clipboard%.txt
Sleep 100
Send, ^o
Sleep 100
Send, ^v
Sleep 100
Send, !o
Return
Edit:
In the script you posted, you are telling the computer to Send a Sleep Key by placing brackets around the word Sleep. Like so {Sleep}
Furthermore, you are also telling your script to not just Send one key... you are telling it to Send the Sleep Key 100 times by placing the number 100 in the brackets, separated by a space, with the named key. Like so: {Sleep 100}
I fail to see how you would want to have your script simulate 100 Sleep key presses?
What I posted above uses the Sleep Command which delays the script in milliseconds. I believe this is truly what you want.
