To support our legacy product based upon the C166 micro-controller we have been using the v3.04 version of the compiler.
I know the compiler is way out of date but since we have moved on from the C166 we just need something to support existing product.
This compiler version is fine on Windows 95/98 but does not work on Windows XP, I think it is down to the way XP communicates with the parallel port.
Anyone got any ideas to try and solve this????
This might help - I've had to do something similar when using dongles, programmers and the like on XP machines before.
