A really noob question here…..

I have only access to visual studio .net, and have created a very simple app that does not require any .net stuff. I find on some older pc’s I get an error when opening my program, I believe that these pc’s do not have any .net runtimes. My question is can I somehow compile my program in .net to be compatible with the older vb6 runtimes or is that just a daft question?

Thanks
