Imam problem oko instaliranja ovog na Xperiu...

Kopiram sve potrebno (2577, drive, maps, res, SetupWinMobile.exe) i pokrenem setupwinmobile.exe.

Pojavi mi se popup i pise: The file " cannot be opened. Either it is not signed with a trusted certficate, or one of its components cannot be found. In the problem persists, try reinstalling or restoring this file.

Sto bi to trebalo znaciti i kako instalirati navigaciju?
