QuickBooks Desktop and Point of Sale Failing to Open Following Microsoft Update

One of the latest Microsoft updates is apparently causing errors when attempting to open QuickBooks Desktop and QuickBooks Point of Sale, or may be causing these programs to crash repeatedly.

Intuit has identified a recent Microsoft patch preventing QuickBooks Desktop products from opening on computers using Windows 7 and Server 2008 R2 operating systems.

Intuit believes that Microsoft's release of the patch KB4074805 for .NET Framework appears to have caused this issue. As a result, QuickBooks Desktop products, including Point of Sale, may not function properly while these updates are installed.

While Microsoft has withdrawn the patch and it is no longer available as a Windows update, it is still impacting those users who had already installed it on their computers.

If you are experiencing this problem it will be necessary to remove patch KB4074805. If you still experience the issue after removing patch KB4074805, you may have to uninstall patch KB4073701 as well.  If you are not comfortable performing operating system roll-backs, please contact a qualified Microsoft IT professional to assist you.
