Firstly, PP2000 standalone will ONLY work in an XP environment. It will also likely not work properly on your 307. If you search the net, you will find loads of people with scanning issues with 307's using the earlier interface and PP2000. This is the reason I made sure I purchased a later Lexia interface version and used diagbox/PP2000 combination software as I had a 307. Also 2003 like yours. It works fine.
You will also need to install the software on a 32bit operating system, NOT 64 bit. It will install but will not function properly... I know, I tried all sorts of things with both win7 64 bit and win10 64bit to try to make it work in the 64bit environment.
Does not work.
I have installed Diagbox in winXP, Win7 and Win10, all
32bit systems and it functions perfectly. XP version is in an ancient IBM laptop, the win 7 and win 10 installs are in newish toshiba i7 laptops. The win7 install is 32bit in the root drive, the win10 32bit install is on a VD inside a win10 64bit installation.
I also purchased my Lexia kit from a supplier in the UK [Easy Diagnostics] as I had already experienced the 'service' from the chinese market when my brother bought a Lexia kit from china and had MAJOR problems with both the interface and the software. My kit installed without any problems whatsoever, software install was 'idiot-proof'... necessary for me as I am an old relic..
