Qt5core.dll Is Missing

[Manases Blakemore]

Icompiled a simple Qt 5 project successful in Qt Creator. When run from within Qt Creator it works.But when i transferred the executable into another location is produces the following error message on the cmd console;

The file Qt5Cored.dll will exist on your system, otherwise it would not work from Qt Creator either. I think it's just Windows search that lets you down. Open a cmd prompt and do a dir c:\Qt5Cored.dll /s

Another note is that those *d.dll are debug DLL's, which means you are distributing a debug version of your application. You might want to build a release version for distribution instead. (In which case you'll need Qt5Core.dll)

For the solution what you need to do is to copy the path of the bin folder in your installed Qt creator. Mine was D:\QTCreator\5.12.10\mingw73_64\bin and then paste it in the Environment variable of your computer (which can be found in your advanced system settings of your PC)

If you have installed Qt Creator you have the missing dlls. Mine were at C:\Qt\5.15.2\mingw81_64\bin. I added the path to my environmental variables and my executable now works. This solution allows you to move your application around without moving dlls.

Errors related to qt5core.dll can arise for a few different different reasons. For instance, a faulty application, qt5core.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry.

In the vast majority of cases, the solution is to properly reinstall qt5core.dll on your PC, to the Windows system folder. Alternatively, some programs, notably PC games, require that the DLL file is placed in the game/application installation folder.

Do you have information that we do not?

Another effective fix for the Qt5Core dll missing error is to manually download the file and place it under the correct directory. Since the Qt5Core dll download packages vary depending on 32-bit or 64-bit architecture, you need to check the system type of your computer.

Step 2. Now, you should find a list of Qt5Core dll download versions. Here we recommend you download the latest version based on your system architecture type. Then click on Download to get the file.

Step 5. Select a directory for the recovered data in the pop-up window and click on OK to confirm the location. Then follow the on-screen prompts to finish this process.

Starting the Simulator for the HMI in Step 7 TIA v14 Basic results in the Simulator screen opening but it hangs indefinitely with an hourglass icon. Attempting to start the simulator manually (by running HMISRT.exe) gives the error "The program can't start because Qt5Core.dll is missing from your computer". I uninstalled and reinstalled the simulator and confirmed that Qt5Core.dll exists in Qt5.1 and Qt5.7 folders.

OK had to install Vista SP2 and then update for Knowledgebase article 2999226

This installed the missing api-ms-win-crt-runtime-l1-1-0.dll file

Everything seems to run ok now. I think I should put this in the Bugs forum as the file needs to be included in the install package.

I also tried DependencyWalker on cv2.cp36-win32.pyd, and it shows that several DLLs are missing, such as API-MS-WIN-CORE-APIQUERY-L1-1-0.DLL. There's also several that are found in my 64-bit MikTex install. Not sure if this matter, but though I'd toss it out there.

Just gave it a try. Re-ran over the last build using the same settings except BUILD_SHARED_LIBS = False. It completed just fine and "cv2.cp36-win32.pyd" is now 19,917 KB. Interestingly I'm still getting the same errors as before. Seems like there is still a .dll dependency. Any other suggestions? Anything else I can try?

Ok, I think I've come up with something. Looking again at DependencyWalker, I notice that some Qt5 files were marked with a yellow question mark (e.g., Qt5Core.dll, Qt5Gui.dll, etc.). I added the path to the Qt5 binaries (since I have Qt5, these are available to me), and what do you know, I can now import cv2 in Python. Here's where I'm lost... why would cv2.cp36-win32.pyd need Qt5 binaries?

DLL or Dynamic Link Library files are vital to both Windows and the apps installed on it. There are several of these published by Microsoft while third parties too develop files specific to their programs, and sometimes a DLL goes missing. This is commonly seen with Qt5Core.dll.

Additional context

I am using the sample code copied straight from the Zoom Developer website (Initialize the SDK), so I am surprised that it does not work as is. I suspect the code samples there are obsolete, and that some necessary steps are missing.

A couple years ago, when I was using an older version of the SDK (when JWT was being used for authorization), I had a similar problem that was traced to a mismatch in the order of function entry points in the DLL. I think my linker was mixing up the entry points and calling the wrong function. I am wondering if a similar problem is happening this time? In the past, I think I fixed it by hacking the associated .h file to change the order of the function declarations.

To quickly resolve your problem, we recommend download and use Qt5Core.dll Fix Tool. If you have technical experience and you want to install a DLL file manually, please select your version of Windows and download Qt5Core.dll, after that copy it to the appropriate place using the instruction below, it will fix dll errors.

Some applications or games may need this file to work properly. If Qt5Core.dll is missing, whenever you start the application/game you may experience various kinds of errors. To fix those errors, please read the Recommended Solution below.

Whenever I click on the RStudio icon an error pops up that says

rstudio.exe - Bad Image

C:\Program Files\RStudio\bin\Qt5PrintSupport.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0xc0000428.

I am new to the community so please let me know what further information is needed and/or proper way to post etc. This occurred yesterday after I updated RStudio and I tried to troubleshoot all day, but I can not figure it out.

I ended up finding that a lot of c++ .dll's were missing (not sure why). So, I wiped my computer and reloaded windows and it works now. I don't know what happed or why it happened. If it happens again I will post it here.

After installing Huggle3.1.1, the login window displays the following error message: Login failed, unable to parse local config for eswiki: template-summ contains no data (no revert summaries).

Huggle 313: view edit in external browser is no longer functioning. One always gets the W main page... Can this bug be fixed please?Super48paul (talk) 14:28, 19 September 2014 (UTC) Correction: the suspect edit shown from the queue DOES link to external browser correctly; only, when you change the diff under scrutiny yourself (for example while there is a more recent one that needs scrutiny), THEN you arrive at the main page of W. So this is half a bug..Super48paul (talk) 14:51, 19 September 2014 (UTC)

Hi, i downloaded the latest version of Huggle and i couldn't connect it via proxy. I am currently using an earlier version for this reason. I hope that as soon as this problem is resolved. Greetings. Pablodiego15 (talk) 15:44, 8 August 2014 (UTC)

I am also experiencing the "intoken parameter has been deprecated" problem using 2.1.23 and cannot revert multiple edits or send warnings. Will there be a fix or a workaround, or do we have to move to 3? BethNaught (talk) 14:18, 8 September 2014 (UTC)

The problem is not, that mw api changes, but that hg2 bails out on every warning, even if its only a deprecation warning for a FUTURE api change.

Huggle 2.1.25 only fixes that for the fetch of the global config, but lot of other querys need also the fix (including local config query and RC via non-IRC). I'm generally working on fixing this, but I have only hardly time for this and/or testing willingness to find all spots. --se4598 (talk) 19:59, 30 October 2014 (UTC)

In Huggle 2, when a user's (or IP's) warning level changed (by being reverted and warned by myself or by someone else), this was immediately reflected in the horizontal Page and User "ribbons" of the Editbar. Alas, this seems not to happen in H3. The change is also not reflected in the User History window. Could this behaviour be implemented both in the user History window, and in the Page and User ribbons of the Editbar in H3? Thanks! - DVdm (talk) 19:51, 29 October 2014 (UTC)

I need a protable version because I am not able to use the normal version of Huggle at work (in my freetime). When I tried it with the normal version, the programm says:"Login failed: Unable to prase the global configuration. See debug log for more details.: Host unreachable"Thank you for helping me.

Ever since I switched to Huggle 3 I've been reluctant to report users. The diffs I select in the report window are never the ones reported to the AIV (unless the user has made no other edits). Huggle 3 seems to report completly random edits by the user instead of the ones I select. (most recent example). I've never had this problem in years past using Huggle 1 and Huggle 2. Is there any way I can fix this? I'm using Huggle 3.1.4. --Seahorseruler (Talk Page) (Contribs) 05:41, 4 November 2014 (UTC)

I am using an older version of Huggle and am not updating it because my university does not let me download EXE files. I've noticed that the Huggle Update notification window refuses to disappear no matter how many times I click on the Close button. --Rsrikanth05 (talk) 19:24, 17 November 2014 (UTC)
