Those of us who bought Stanford Wong's Tournament Blackjack Software years ago have found that modern 64-bit computers can't run it. On my Windows 10 laptop I can't even run it as an administrator, or in compatibility mode. There is a workaround, for those of you who still have your old copy of this software. You use the open source program VMWare Workstation Player to set up a Windows 98 virtual machine in your computer. You have to have a licensed copy of Windows 98 to do that. A virtual machine is a window running in your computer that is actually acting as a second computer. If you don't already have an old copy of Windows 98 or other old operating system disk, you can obtain one on eBAY for a nominal cost. https://www.ebay.com/sch/i.html?_fr...RS1&_nkw=windows+98+operating+system&_sacat=0 Then you download VMWare Workstation Player from VMWare's website for free. https://my.vmware.com/en/web/vmware/free#desktop_end_user_computing/vmware_workstation_player/14_0 Install VMWare Workstation Player. Then open it and set up a Windows 98 virtual machine. You have to download the VMWare Tools within the virtual machine. This video does a good job of walking you through the whole process: I found that to get my Tournament Blackjack Software files into the virtual machine, I had to make a new folder on the Desktop of the virtual machine, and then copy the files from File Explorer in my Windows 10 host into the new folder in my Windows 98 virtual machine. It would not copy the folder from my Windows 10 host to the Windows 98 virtual machine directly.
