When I try to launch Syn3 updater I get an error Message “Invalid Class”. I have a Toshiba Windows 10 laptop. How do I correct this error?
SYNC Region: NA
Navigation Variant: Nav
Manufacturer Year: Pre MY20
Install Type: OEM
Old SYNC Version: 2.2
New SYNC Version: 3.4
Do you have a error message, if so what is it?
Invalid Class
Update Method: CyanLabs Syn3 Updater
Syn3 Updater Version: Syn3 Version 2.0
Syn3 Updater Documentation Read: yes
Syn3 Updater Log File
Can not find log
Is it Windows 10S by chance? Is it fully up to date?
Pop open a command window in administrator mode and type :-
sfc /scannow
and wait for completion, If it states an error then type :-
Dism /Online /Cleanup-Image /CheckHealth
and wait for completion.
Searching “invalid class” would get you your answer 
Tried this too and it came back with no error. What now?? I really want to update my Sync3 and navigation maps but don’t want to pay the ridiculous price Ford charges. Any help would surely be appreciated!
