I just upgraded from a dell D800 to D820, running XP Pro. I have an important piece of software writting in a vintage program called Mapper for Windows, which is 16-bit. When trying to execute the software, I get "The Handle is Invalid". I can get around it by right-clicking the icon and choosing "run as" and then running as administrator. But not sure why. I installed the software with my normal log on and my normal log on has full admin priviledges.
I had thought it was a problem with the Embassy Trust Platform Dell included. That had caused a problem before with the same software, so I fully removed it. But nothing improved.
Any ideas?
