I found the similar question here for VS2010 with the answer that there are should be no spaces in the paths. But I dont have spaces in the paths.

Do anybody know why the abowe issue happens and how to fix it?

Answer 1

It seems, that 2.6.0.6 version of VS Qt Addin is broken . Fixed this issue by disabling automatic extension updates in Visual Studio options and reverting to the 2.5.1 version

Answer 2

Correct, but it is fixed in Version 2.6.0.7 .

At least for me the problem was solved with this update.
