Which I think is about 3 years plus old but it was on my old computer which died. I have now recovered the drive at the bitcoin-qt application but it won't run on my current computer either due to the operating system or some other issue. The problem is that I don't have the wallet.dat files as I never generated that back on my old computer, so really need to run the old application in order to generate the file. Any suggestion on how to proceed? Is this an issue of finding an old version of the operating system and run the application file there or what other approaches should be taken?
Any help would be much appreciated
