my laptop is older I think at best its usb2 or maybe usb 1.1 . it shows as ..usb serial port (com1) in device manager I have tried using lower com ports, clearing the ports and trying again. I was getting... unable to connect to com port 1 error 5 on various ports.
i tried different software but still no connection.
I will delete all drivers today and do a manual install

What version of windows are you using (both main windows version, and is it 64 bit)? Usually usb 3 ports have a blue central bit, though not always the case.
It might help to right click the program your running and select run as administrator if your using windows 10, as error 5 translates to access is denied I think. Given the software doesn't really install it may not have sufficient rights to access the com port, though think its a long shot there.

If you open the command prompt, have the interface connected and type the following command into command prompt window what response do you get (doesn't need to be connected to the car when you do this, just plugged into the pc is enough)

Copy con com1

Type in anything here - test will do

Then press ctrl-c on the keyboard

If the port doesn't exist it should give cannot find file specified.
If it does work it should say 1 files copied

If something else is wrong, it should give some idea whats going on.

if its not on com1 currently change the com1 to suit what its currently set to.

Type something into the flashing cursor bit - anything at all doesn't matter what and then press ctrl-c. That should give you some sort of response about either copying files or access denied or similar.

any different if you use an administrator command prompt? (create a shortcut to cmd.exe and then right click that and choose run as administrator).

Its probabbly just down to the way windows 7 reports it, but thread exit should be down to your pressing ctrl c - do you see 0 files copied or 1 files copied? Your post above says 0, if thats the case i'd suspect something is not right with your interface (all this command is doing is sending your keyboard input to the com port, it doesn't check its been sent anywhere as such, just proves if its possible to write to it - which it should be).

If you plug your usb cable into a different usb port, it might have added another com port rather than using the one you set before - check device manager with the cable plugged into the laptop and see what its set to (or set it to com1) and then try it again - if you get 1 files copied thats a start at least, as it proves the com port does actually work in windows.

That solution is for a database - its not relevant to your problem as you don't have that software on your machine. hence the command doesn't work.

I notice in you command prompt picture it says 1 files copied on com5 so your computer knows the cable is present
even on my pc it never recognises the cable as it wont copy a file on any com port

That does sound to me like something is wrong with either the cable or the drivers. Mine isn't the exact same cable, but should behave in the same way as far as i know (the one i tested with is an ftdi chipset one for KME, FTDI make most of the interface chips for this sort of thing so should be the same).
