InsertVBComponent not working

Good day all.
To say I am frustrated is an understatement. I am pulling my hair out. I have a piece of code that works when I run it manually via the VBA enviroment works, but as soon as I need it to run by itself it just does not run. I am frustrated to the point of pulling my hair out.

Just to get some of the obvious things out of the way,
1) I tried running it in the workbook open process (failed)
2) I tried running it as a sub connected to a button (Failed)
3) Yes macros are enabled
4) Yes the vba environment access is enabled in macro settings.

I cant pay someone to help me with this so I am appealing to the community to PLEASE help me

Just show 'it'.

Im not sure if I am allowed to attach the workbook but here goes.

or here is the raw code:

Module1:

Option Explicit
Dim Msg_Box_Answer As Integer
Dim counter As Long
Public Const SheetPass As String = "Pass"
Dim Driveletter As String
Dim VerNum As String
Function Read_From_File(Path As String) As String

'PURPOSE: Send All Data From Text File To A String Variable
Dim Filepath As String
Dim TextFile As Integer

'File Path of Text File
Filepath = Path

'Determine the next file number available for use by the FileOpen function
TextFile = FreeFile

'Open the text file
Open Filepath For Input As TextFile

'Store file content inside a variable
Read_From_File = Input(LOF(TextFile), TextFile)

'Close Text File
Close TextFile

End Function

Dim FindDriveLetter As String

Set dc = fs.Drives
For Each d In dc
If d.drivetype = 3 Then
If UCase(d.sharename) = UCase(shareToFind) Then
Find_Drive_Letter = d.Driveletter
Exit Function

Next

Use an AddIn instead of this code.

Sorry, I have no idea what an AddIn is.

Would that allow me to change the background code and so forth? I will also youtube to learn more about AddIns.
