Cannot Connect to QML Emluation Layer (QML Puppet)

Question

I just made the fresh QT installation and when I create empty QT Quick project or open any of existing QT Quick examples, my QML designer doesn't work. It shows "Cannot Connect to QML Emluation Layer (QML Puppet)" error.

I tried to reinstall QT, reboot, installed additional QT kit versions and tried to switch between 32bit/64bit default/opengl versions of the kit and nothing seems to work for me. I was able to successfully run the designer ONCE, and after I closed it and tried to re-open the file it stopped working again. I also tried to search, but didn't find any solution. I also tried to ask on QT forums, but didn't receive any answer.

My system is Windows 7, with Visual Studio 2013 installed. Thanks for your help!

Answer 1

Do this:

• Go to QT Creator Preferences (Menu Bar | Tools > Options)

• Select QT Quick Option (Options headings - left side).

• Click the QT Quick Designer tab.

• Under QML Emulation Layer grouping, select "Use QML Emulation Layer that is built with selected QT".

No need to choose a path,

• And click OK.

It will rebuild your designer view. Worked for me.
