OSGeo4w installer fails: unable to extract /appa/qt5/bin/qt5webenginecored.pdb

Question

I am trying to install OSGeo4w. I have plenty of RAM and disk space, running Server 2016 standard. Installation fails with the following log:

UPDATE

The answer below didn't resolve my issue. After installing Qt5 and running OSGeo4W setup again, I receive the same error. Additionally, after cloning the repo found at https://codereview.qt-project.org/admin/repos/qt/qtwebengine and running the OSGeo4W install again for the qt5webenginecoreed.pdb, error persists. Research shows that the debug file was no included in the 64-bit build, so I'm guessing that is the problem. Moreover, I don't know if this will affect the functionality at all either as my impetus behind the install was for python functionality with the gdal module.

END UPDATE

I'm having the same issue and ran across this thread related to the qt sdk. I don't know if it will help, but it does point in the direction of Qt5 install. If it works for me, I'll try to post back here. Really surprised your question has gone unanswered for this long.
