Step 2 - Append Your Entry To APIIMPLEMENTATIONS
If the file does exist, retrieve the string for the key APIImplementations using the GetPrivateProfileString () function. Scan the returned string to check if it contains "AAARP32". If it does not, then append the string ", AAARP32" to the end of the string that was returned and overwrite the APIImplementations key value with the newly appended string.
