[PyQt] QtWebEngineProcess.exe: missing VCRUNTIME140.dll

[Ales Erjavec]

Hi,

Installing the current PyQt5 5.8.1.1 wheel distribution into a user
installed Python
environment (3.5.3) that was not added to PATH (during or after
installation), can leave
a non functioning QtWebEngineCore/Widgets if/when the msvc
redistributable dlls are not
installed (somewhere on PATH).

Using the QWebEngineView results in a familiar "The program can't
start because some.dll is missing from your computer...".

Copying the vcruntime140.dll into ${sitepackages}/PyQt5/Qt/bin next to
QtWebEngineProcess.exe fixes this.

Considering that the PyQt5\Qt\bin directory already contains
{concrt,msvcp}140.dll
redistributables, is it possible to also add the vcruntime140.dll in a
future release?
