The program runs OK on the PC it was designed on. When using application wizard and load it on another PC we get the error "Can't open a database created with a previous version of your application". We have VB 4.0 installed on our PC's, but not on the PC that we are loading the application on. All PC's involved using NT. We cannot remove VB 4.0 from our PC's at this time. Does anyone know how to get around this?
