Why Won't Money Plus Sunset Deluxe Open In Windows 8?

Based on the articles researched, it sounds like a compatability issue.  As of this writing, Money Plus Sunset Deluxe works with Windows XP, Vista, and Windows 7.  You can try running the software in compatability mode for an earlier operating system.

• Right click on the icon for the program, and choose PROPERTIES.
• Look for and click on COMPATABILITY tab.
• In the first section marked COMPATABILITY MODE, check the box "Run this program in compatability mode for:".  The drop down box below it will become active.
• Select an operating system from the list (start with Windows 7)
• Check the box at the bottom that says "Run this program as administrator."  Click APPLY then OK.
• Try running the program again. 

If it doesn't work, then the program in its current form is incompatable with Windows 8.  Check back with Microsoft's website for updates.  Good luck.
