Bimmer Scene - Latest BMW Coding / Retrofits / Maps

Hi,

I installed ista+ 4.32.15, but when I try to connect to car i receive message 

"the vehicle identification number could not be determined from the vehicle. please enter the 7-character or 17-character vehicle identification number to continue"

What is wrong?

ISTA installation incorrect, use CC cleaner or delete Registry file and install again.

Thanks. Will try again then.
