Error "The procedure entry point CreateEvent could not be located" during installation of Qt C++ application on Windows 10
-
Another indication that the screenshot is from a Windows 7 PC: that error dialog "... - Entry Point Not Found" still gave you information about which .dll that failed to export that symbol (i.e. api-ms-win-core-synch-l1-2-0.dll)
But Windows 10 (and Windows 11 etc.) instead, for the same error, states which file (usually an .exe) that failed to import the symbol. So if this really was a Windows 10 desktop, the error message should have been:
"The procedure entry point CreateEventW could not be located in the dynamic link library Elab_license_otp.exe"BTW: I think this is regression since it still says: "dynamic link library" :-(

@hskoglund No sir i will post

I no longer understand. Your first post states "during the installation process on the target Windows 10 machine", your screenshot (according to @hskoglund) shows Windows 7, and now you seem to say you did install on Windows 7 after all. It is difficult to be sure what you are saying.
At this point you need to:
- Write the absolute minimal Qt program, 10 lines long.
- Build for Release.
- Use windeployqt to create an installable image.
- Install on a Windows 10+ machine, preferably one which has not been upgraded from Windows 7.
- And if possible install on more than one machine, to rule out something on that machine being the issue.
You can see that people are running out of useful ideas to help. You can Google for
The procedure entry point CreateEventW could not be located in the dynamic link library api-ms-win-core-synch-l1-2-0.dllas I have done, there are a couple of hits.
If your development machine runs the same Windows version as the one with that error you could find where
api-ms-win-core-synch-l1-2-0.dllis on both machines, compare the date/size/versions of those two, run Dependencies on both to see if the "bad" one is missing dependency. -

Hello
As you said PF screenshot of error getting on windows 10 pc , where as file mention in error is available in directory.
@Tusharn
While it is true that I cannot spot why you get this error message given the directory's contents, this is a quite different error message from the one you said you get, you show at the top and we have been discussing throughout this topic. Why are you now getting a different message if you said Win 10 gave you the original message? Is this a different Win 10 machine from the one you said produced the first error? It is difficult to help when you report one thing and then show something different.....It is possible that you could get the latest error message if the named DLL is missing one of its dependencies. You might like to load up the Windows Dependencies tool to examine this.

Hi, just guessing but that missing dll error can occur if your app for example starts a printout and that Windows 10 PC has a older (perhaps not Qt) installation of MinGW that lacks libgcc_s_seh-1.dll and that other MinGW is in ithe path environment variable.
To check, try building a simple app, say the Calculator Example using your MinGW 6.5.1. Then use the same windeployqt procedure you did for Elab_license_otp.exe and try the Calculator app on that Windows 10 PC.

@hskoglund now i am run application on windows 7 & 10. I tried as you said but getting same error.

I wrote application on windows 11 and find way to deploy it correctly, but on windows 7 this app doesn’t work and go to same error as yours. I try to reinstall dlls, sfc /scan, Visual Redistributable but still nothing. I try this app on windows 10 if it works

Anyone tell me which version of qt creator is stable for windows or suitable for windows 10
@Tusharn
Are you really asking about Qt Creator version here? Do you understand that it is the Qt version, nothing to do with Creator, which determines whether your application will or won't run under Windows 7, 10 or whatever? So far as I know any version of Creator will run under Windows 10.
