Multiecuscan

I'm having trouble connecting with a sony vaio laptop, running win7, using an ELM cable. I have the multiscan v5 loaded. I'm looking to migrate the software from a large laptop to this smaller one.

I have plugged a usb mem stick and confirmed that can see it so I think the usb port is working. I have an ELM cable I know works from another laptop running xp.
With the working ELM cable plugged in, car key switched on, I try scanning in multiecuscan, it reports "Index was out of range, Must be a non-negative and less the size of the collection". Unsprisingly, When I 'test' the interface it just says it has timed out and when I connect it say connection failed, the operation has timed out.

Any Ideas please ?

is .NET installed?

yeap, .net 3.5

i dont get it. I must be missing something pretty basic.

check adapter whether it's seen in device manager, check if drivers are installed for adapter. make sure laptop also has all drivers installed. not sure what else to suggest.

Yes, that sorted it.

In 'Device Manager', it said FT232t USB serial not working.

I downloaded my driver from
https://www.usb-drivers.org/ft232r-usb-uart-driver.html
and followed their instructions.

PLEASE check URL yourself that it is not a dodgy site. Seemed OK for me but my laptop is only for my Doblo ECU
