As you will probably concluded I'm new to programming. I've purchased a MCB900 board and attempting to program. I've loaded Measure C sample program and attempted to build it.I keep getting an error messgae that it can't execute C:\LPC900KEIL\C51\BIN\C51.EXE. I made a folder LPC900KEIL in which I installed all the information from the CD. Any suggestions would be greatly appreciated.
