Building Adapter for QT Quick Application Fails on QT 5.12 Offline Installation

testingcodehere

Hi,
I'm new to QT and i'm learning through the tutorials.

I was following the Quick Application tutorial and i noticed my QT Designer view in QT Creator wasn't working. I followed a few workarounds online and enabled QML Designer.

But when i start the QT Creator design view it says "Building Adapter for Current QT" then fails with a error.

my qt installation is at: E:\MyTools\qt\qtoolkit

I've tried retrying again and reinstalling it too.
