    Default Imediate Program Crash

    I hope this is the correct forum for this subject. I believe that this is probably an installation problem.
    I recently upgraded to 5.7.0 from Qt 4.7.4 and I was having some problems. I did not remove 4.7.4 prior to installing 5.7 so I thought that might be causing the problem. I uninstalled both versions and then re-installed version 5.7. This is the environment I'm now attempting to run in...

    OS: Windows 7 – Service Pack 1
    System: 64 bit Operating System
    IDE: Qt Creator 4.1.0
    Qt Version: Qt 5.7.0
    Compiler: MinGW 5.3.0 32 bit
    nMake: Using jom instead of nMake

    I attempted to build a quick bare-bones program from Qt Creator to test the install. It built just fine but when I went to run it, or run a debug version, the program would crash immediately. In debug, I set several breakpoints, including the first line and execution wasn't even reaching the first line of code. Running several of the provided example programs gave the same result.

    I have searched the internet extensively and have not found a solution, or any one else experiencing a similar problem.

    Thank you in advance if anyone can provide some insight on this problem.

    Following are the details along with the bare-bones code that I first experienced the problem with.

    ui->hellViewWidget->addItem("GoToHell");
    I guess the Qt runtime finds your program to be offensive.

    My other guess is that you don't have the Qt 5 and/or mingw DLLs in your system path so the runtime isn't finding them at startup.

    Thank you d_stranz for your reply.

    Your correct, perhaps the code may be offensive to some. So I burned some candles and performed some chants and deeply apologized to the Qt run-time.

    Actually I have since uninstalled all Qt items and reinstalled an older version (4.8.3) and I'm giving that a go. However as soon as I get past this little time critical issue, I'm planning on attempting another try at 5.7 and I will ensure that the Qt 5 and MinGW DLL's are in my system path.

    Thanks again for your assistance, I truly appreciate it.
