Compile error: Type mismatch (converting 32bit to 64bit VBA coding) - vba

Question

This is my first time using VBA so I need help. This is a macro in Excel to convert a file from one Excel extension to another. I have starting converting this code from 32 bit to work in 64 bit and found online most the key parts to change but now it is giving me Compile Errors: Type mismatch and I have no idea what to change. Any help is appreciated.
The Error shows the yellow arrow at Sub loopConvert() and the cntToConvert as the blue highlighted section. Picture included.

Answer 1

Squidx3 helped me figure out that I needed to just change it. It works now Thanks!
From this:
Dim numconverted As LongPtr, cntToConvert As LongPtr, i As LongPtr
To this:
Dim numconverted As LongPtr, cntToConvert As Long, i As Long

GetFolderName isn't a native function. You copied this code from another place? Verify if getFolderName is there.
