I suppose what I did was, when prompted for the file association in the VB Converter tool, I just stuck .exe in there, not really understanding what it was asking for (especially since my program has no file associations) and this is the result. My guess is that the culprit are the following few lines:

# Remove file extension to open the program.
    DeleteRegKey HKCR ".exe"
    DeleteRegKey HKCR "MyProg-Standard file"
    Delete /RebootOk "$SMPrograms\MyProg\MyProg.lnk"

With that said, I tried the following solutions.

I tried the solution presented here which had seemingly no effect.
I tried a couple of the solutions here as well. EthanAD's solution did nothing for me either. However, running assoc .exe=exefile did work for me on one PC (the one which I was testing the installation on). But it did not work on the computer which compiled the NSIS script and the one running my development environment. On that one, in trying to fix the issue, I believe I selected Notepad to be the default program for opening .exe files in my haste to solve the problem. Now, every program opens with Notepad (I even opened Notepad itself with Notepad). Running assoc .exe=exe on that PC has no effect, even though running assoc .exe and ftype exefilereturn the correct results (.exe=exefile and exefile="%1" %* respectively).

Can somebody help me restore default Windows functionality with regards to EXE files?

--- EDIT ---

To clarify, this is not a duplicate of this question, I've tried it (as an admin) and it did nothing.
