Pixinsight System error

[chemstock1]

downloaded the latest version of Pixinsight (2015-12-15) from the web, installed and ran OK. It indicated 5 new updates, installed those and get this error:
"The program can't start because Qt5WebKitWidgets.dll is missing from your computer" Try reinstalling.
Downloaded and reinstalled the 2015-12-15 version and still have the error.

Windows 10 (arrghhh)

Bit of an update..
uninstalled program and reinstalled.  Same error when accessing program from taskbar or desktop.  Used file explorer to search for the Qt5... file and it was there. Program started when I clicked on the application directly from file explorer.
Deleted taskbar and desktop icons and created new ones.  Program runs.

Likely a Windows 10 issue

We cannot reproduce this issue on any supported Windows version/machine, including Windows 10. This does not happen under normal working conditions.

Anyway, glad to know you've found a solution.
