Here's a slightly edited excerpt I received from a potential buyer:

"An editor is planning four small book/CD packages over the next 12 months... These CDs would have to be cross platform hybrids for MAC and PC. If you’re interested, can you give me cost estimates as soon as possible?"

I responded that I was unaware of any single language or installer that would work "out of the box" with Windows back to '95, Vista, and all Macs. I was told that the product would have to do that in order to bid on it. I advised that it would be best to supply two separate CD products, one for Windows and Vista and the other for the Mac.

Being a VB6 programmer (and potentially Vb.net) and an App developer for Windows and Vista, was I correct? Please advise and TIA.
