Hi!!!
I want to know difference between houdini vc14 (normal download) and houdini qt4 version…
houdini vc14 version seems to be normal download version….
And houdini qt4 version seems to be new in download section…
what is qt4???
I don't know which version I have to install…
Need help…

If you don't know, you probably don't need it.

just install the vc14 version - the qt4 version is for those who are not able to upgrade to qt5.

Afaik it's for those who wrote C++/Python plugins that rely on version 4 of Qt.

Qt5 also uses PySide2 so old PySide code also needs to be updated somewhat if you want to run it in the Qt5 builds.
