I have a dell dimension3000 running WinXP. I use Paradox 4.0. I purchased an iMac last year and have been jumping through hoops to try to get paradox to run on the iMac. I have parallels. Doesn't work. I bought win7 and installed on iMac. Same result.
Is there a way to run the hard drive on the iMac or run it on an inexpensive laptop?
Is Virtualbox the answer?

You are running a very old piece of software here. Paradox for Windows 4 was designed for Windows 3. (I presume you mean this rather than the straight "Paradox 4.0" which was a DOS program.)

Having said this, I am still using Paradox 7, which is a little newer, but only by a couple of years. That was marketed for Windows 95. It is usable on Windows 7, though it is a little unstable and sometimes crashes out. It works better on a virtual machine in VirtualBox, though I myself normally use Windows 2000 rather than XP. You clearly have been using Paradox 4 successfully on Windows XP.

If it works on a physical Windows XP machine, it will almost certainly work on a virtual machine running Windos XP in VirtualBox, though no-one can give a 100% guarantee.

There is a small glitch in the installation routine of Paradox 7 (I don't remember about Paradox 4). It requires just over a Megabyte of space for installation, but if your hard disk is too big (over about 500Mb) then something goes wrong and it thinks it hasn't got enough disk space! The solution is to add another small hard disk and point the "TEMP" enviornment variable to it. You can reset it after the installation.
