@tiptipon Hi, if you're stuck at 41% that usually indicates that there's an issue with the Direct X or vcredist packages that are part of the game install.
These write files to the critical sections of your Windows Operating system so permissions issues or problems with Windows itself can be a factor. If you try running these files manually do you run into any issues?
They can be found in your games install folder at:
\Apex\__Installer\directx\redist
Run DXSETUP at this location and please check if it completes without issue or fails.
\Apex\__Installer\vc\vc2010sp1\redist
\Apex\__Installer\vc\vc2012Update4\redist
\Apex\__Installer\vc\vc2015\redist
Run the various vcredist files you'll find in each location and see if any of them fail.
Thanks.
