Hi Chris,
I have followed both solution non work , i have windows 7 32 bit , i found one thing in environment variables of PATH in new QT was
D:\SDK\FelgoSDK\Desktop\Qt\4.8.1\mingw\bin;
D:\SDK\FelgoSDK\mingw\bin;
while in old one it was
D:\SDK\FelgoSDK\mingw\bin;
D:\SDK\FelgoSDK\Desktop\Qt\4.8.1\mingw\lib;
D:\SDK\FelgoSDK\Desktop\Qt\4.8.1\mingw\bin;
So i have edit the environment variable in new QT creator and compiled it it runs fine as before it compile fine as before but still QML module not found and Vplay header file seems unable to find through editor like i wrote in my previous post.
Then i have closed and then re open it again still same issue.
I clicked on RUN to see Build environment variables
