Windows 10: Help Finding Repairing or Replacing Files "Qt5Gui.Dll", "Qt5Core.Dll", and "Qt5Widgets.Dll"...

title sums up the jist of it. im a pc gamer that doesnt know much about computer repair. recently has a huge Nintendo fan i tried to install the dolphin emulator to play games like metroid prime and super mario sunshine as well as get into competitive melee. however when i unzip the emulator and try to run Dolphin.exe i get 3 error messages consecutively after another. "The code execution cannot proceed because ___ was not found. Reinstalling the program may fix this problem." the blanks were filled with Qt4Gui.Dll Qt5Core.Dll and Qt5Widgets.Dll i did some research but i can only find out what these programs are used for not how to fix them. i would like to go about a way were i can repair this issue for free and not pay for a company to scan my computer and fix it. allthough any help will be apreciated. I already downloaded Visual C++ 2015 and still nothing....

how can i replace a system dll file

hi i change a few of vista tool bars color, i need to replace a dll file but it always in use any way of doing this?

 

Update the mnyob99.dll file


Using 2007 Home & Business Sunset. I have spent over 10 hrs. trying to find the correct fix, including purchasing Quicken and importing 15 years of data into that monster. What a nightmare, but the learning curve to use Quicken vs. continuing to find a Money fix brought me back to my efforts to repair Money. Ultimately, replacing the .dll resolved the issue of crashing. The crash always would occur once the program was fully loaded. Many thanks to Raymond Chen and Ameridan for providing links to the rewritten .dll and step by step instructions.

 

Rundll32.dll?

Make sure to use an adminstrative command prompt.

Try this: ICACLS "c:\windows\system32\rundll32.dll" /T /grant Everyone:F or ICACLS c:\windows\system32\rundll32.dll /T /grant Everyone:F
Can't remember if it is with, or without, quotes.

But, why do all this... try FileAssassin by Malwarebytes, if you are trying to delete the files, but be careful, if you delete the Rundll32.dll files your OS may take a cr*p on you.
