so, i made a litte script to patch your own Renewallib.dll
You have to be use autoit for this. I could make a exe-file for patching, but since i never trust download exe-files i decieded to post the source 
ATTENTION: Backup your original DLL !!!! Every Avic has its own DLL !!!
Bevore pasting the patched DLL back to your AVIC be sure to delete the DLL in the AVIC, because Testmode do not overwrite files sometimes (that was my mistake an i wasted 4 hours on this issue) !
Functions are copied from Autoit forum and only the specific lines for patching are from me 
Here we go:
#include <MsgBoxConstants.au3>
#include <FileConstants.au3>
#include <WinAPI.au3>
