Hi I want to run a freeware calculator from my menu system in AutoCAD 2004. I run the exe from menu it works, however my first dialog errors and says Cannot Open file applications/calculator/calculator/Calculator.exe") but then I select "OK" in error dialog box it then proceeds to open the application. this is what i have in my menu; ID_Calculator [ &Calculator](startapp "c:/my programs/applications/calculator/calculator/Calculator.exe") I run the application outside of AutoCAD and it works fine. I am wondering if its the file path messing it up??? any suggestions? I actually find the calculator quite handy when working in autocad the url is [URL]http://members.tripod.com/plamentd/downloads.html[/URL]
