Hello,

I´m using a Dell laptop (Core i7, 16 gb ram, Nvidia gpu, drivers up to date, Window10 Brazilian Portuguese). I have updated Windows 10 to the latest version (2004) and the NVidia driver too.

I´ve been using Slicer for quite some time and it was working fine.

Since yesterday it began presenting problems. At first, it would crash at start up. It went past the welcome screen. The app window would open, but remained blank, just with the title in the upper bar [“3D Slicer 4.11.0-2020-05-22 (Not responding)”].

Then I replaced it with the latest nightly build (4.11.0-2020-06-01). I kept receiving messages saying a series of dll files were missing (Qt5Core, Qt5Gui, Qt5Network, Qt5WebChannel, Qt5WebEngineWidgets, Qt5Widgets and Qt5Xml). I downloaded these files and copied to the System32 folder. Now I get the error message “0xc00007b”.

The 4.10.2 version works, but I would like to use the features in the newer versions such as Dynamic Modelling.

What should I do?

Thanks!
