    Hi,
    Every time I start Qt Creator I get the following warning message:
    Capture.PNG

    I reinstalled Qt Creator 3 times with or without antivirus running and keep getting the message above. How can I fix it?
    Thank you for your help.

        Hi,
        I tried to find it but as it looks there is no vscode-lldb on my whole computer.

            Do you have Python installed?, seeing as you are missing python36.dll, try reinstalling python.

            NOTE: there is no lldb-vscode.exe on my PC either.

            Don't just sit there standing around, pick up a shovel and sweep up!

            I live by the sea, not in it.

              @gabor53 You should install the current version (4.10.x)

                I solved the problem by installing Python and copying python36.dll into the folder.

                    @helicron I downloaded Python 3.6.8 and moved the python36.dll to my QtCreator/bin folder (C:\Qt\Tools\QtCreator\bin for me). Now it doesn't show the error anymore.

                      It seems like the error is misleading. I got the same error and fixed it by removing LLVM.!

                        that error is related to LLVM. It pops up when QtCreator tries to load lldb (the LLVM debugger) that crashes because of the missing dll. You can verify by opening a command prompt and typing lldb.
                        I don' know why someone decided it was a good idea to package llvm without a required dll but here's how i fixed the error:

                        • dowload a python 3.6 prebuilt package like https://www.python.org/ftp/python/3.6.4/python-3.6.4-embed-amd64.zip
                        • copy python36.dll to the lldb.exe folder (where lldb in a command prompt, mine is installed in C:\Program Files\LLVM\bin)

                          Hi @carcass,

                          as stated in QTCREATORBUG-23848, it's a LLVM packaging problem, which is tracked on https://bugs.llvm.org/show_bug.cgi?id=44087

                          Unfortunately, not much progress seems to happen there.

                          Regards

                          Qt has to stay free or it will die.
