i've been using winpic and my jdm programmer for several years under xp pro without a problem.
My hardware died a horible death and i was forced to upgrade everything (expensive!)

i come to install winpic800 and windows 7 refuses to use a driver that is not digitally signed...
Ergo, i can't program chips and this is kinda bad...

I've got a melabs programmer on order but it's coming from the states to UK and thus will take over a week!

Two solutions i can see...
1) find some other windows 7 compatible software...

2) my laptop has win xp but the serial port is +- 5V and not 12V thus does not have the correct voltage. can i connect an external battery to the JDM to bring the programming voltage up? if so, where to connect it and what voltage do i need?

Any help appreciated... Thanks
