Well, after months of this issue and ignoring it, I found this thread to attempted to fix it.  I did the following which eventually worked.

1) Uninstall Quickbooks from the control panel and everything else that said Intuit or Quickbooks in the uninstaller.

2) Restart

3) Install from downloads.quickbooks.com and run all updates

4) Restart

>>  Quickbooks Database Manager continued to not launch from the shortcut in my start.

5) I went to the Quickbooks Database Manager shortcut which took me to C:\Program Files\Common Files\Intuit\QuickBooks

6) I then clicked on QBServerUtilityMgr.exe and that did work!

7) I then created a new shortcut of QBServerUtilityMgr.exe and called it QB Database Manager

>> That worked for me but your mileage might vary!!  Good Luck!!!
