Using Win 2K and V5R1 WDT - loaded Distributed debugger SP1 and now when attempting to debug RPG pgm get "Internal Error(1)! Could not start debug engine." I've found out the hard way that if you remove IBM Distributed Debugger (it is a seperate installed program in windows add/remove programs list) that trying to remove/amend WDT installation after that no longer works - it just sits there when trying to uninstall/update the debugger. How am I meant to remove this SP1 service pack? thanks
