Why does not Qt5 addin work in Visual Studio? - visual-studio-2013

Question

I have following configurations on my pc-
1) Visual Studio 2013 64bit
2) Installed QT5.4.2 64bit with openGL
3) Qt5Package addin
After installing the addin, it shows up on the menubar like this-
But I can not configure anything as none of the menubar options in QT5 works. I mean when I click a menu item it does not do anything.
I tried to uninstall and reinstall the addin, but still having the same problem. What is the solution to this problem?
There was this error message which appeared only once:
And in the ActivityLog.xml file I found this-

Answer 1

The Qt5package addin avaiable in Visual Studio Gallery has dependency issues. So you need to download the full addin package from this link.

Answer 2

The full addin package doesn't work in Visual Studio 2015 so I used Qt5Package.
I had the same problem with the Beta version of Qt5.6.0. I found a workaround - in C:\Qt\Qt5.6.0\5.6\msvc2015\mkspecs\common\msvc-desktop.conf Qt 5.6.0 splits all the version-specific changes into a separate file msvc-base.conf. If you copy the contents of this file and replace the line "include(msvc- base.conf)" in mscv-desktop.conf then Qt5Package recognises the Qt 5.6.0 Beta with no problems.
Note this still needs to be fixed in Qt5Package.
