Welcome, LOL, Get in line, ha-ha-ha-, sorry, I am joking, but there are only 20 to 30 treads about this already, each containing the solution.

The problem and solution are simple; Your PC automatically installed IE11 during an automatic Windows update.

Roll back to IE10, and problem solved. => Windows restore to a date before the IE11 install.

And go to the Microsoft site to install the little patch that prevents the unwanted installation of IE11.

Poser 10 and PoserPro 2014 are "fail safe" to this IExplorer 11 masacre since SR2. And we are now on SR3 : build 26066.

There is a SM patch to cure Poser9, but the patch to cure PP2012 is not out yet.

The problem surfaced when at release, IE11 broke the older Poser versions, but not all PC's get this automatic IE11 update at the same time.

Poser 1, 2, 3, 4, 5, 7, P8 and PPro2010, P9 and PP2012, P10 and PP2014 Game Dev
