I just moved the software to a new 700 Mhz computer for a client and now I get a runtime error when I run the compiler. They really prefer not to buy an upgrade if it can be avoided since they will not be doing any new development on the older compiler. I have no problems with the hi-tech C that they just bought but they still need to run the old compiler for the legacy code here until everything gets converted over. Does anyone know of a fix or work around for the problem. It ran fine on their older system so I think the configuration and setup are correct. As always any help is appreciated. Larry Larry G.
