installer does not work because of missing DLL

• Jan 31, 2019 - 22:31

Hello, friends.

Thank you for all your tremendous help with such a wonderful program as MuseScore.

I have been using MuseScore 2 for about one year successfully on Windows Vista Ultimate 32-bit OS, and now I am trying to upgrade to version 3.0.0 or 3.0.1. The downloaded installer is called "MuseScore-3.0.0-32bit" or "MuseScore-3.0.1-32bit".

Once installed, the program file is called "MuseScore3.exe", but when launched, I get the following error message: "This application has failed to start because api-ms-win-crt-runtime-11-1-0.dll was not found. Re-installing the application may fix this problem"

Of course, re-installing never helps. Can anyone tell me how to fix this problem without changing my operating system?

FYI, I have 4GB of RAM and a 3.3Ghz processor.


Sadly, Vista cannot be supported by any version of QT that will allow building the program. You will have to continue to use version 2.x.

I don't know that QT stands for anything. It is the interface used by MuseScore to allow it to be used by so many operating systems. In the Help menu there is an About QT window, and nothing in that window says QT stands for anything. It can't be Quick Time because there is no doubt Apple would sue to maintain it's brand name.

Oh, I see. Unrelated, then.

By the way, guys, the link sent to me was for Visual C++ 2015, but it seems that I already had Visual C++ 2017 installed. I did a "repair" installation of 2017 and got this message:
"The procedure entry point GetDisplayConfigBufferSizes could not be located in the dynamic link library USER32.dll."
This, of course, was a different error message from the other.
I have not tried the 2015 version yet (would have to uninstall the 2017) but if you think it makes any difference, I will.

Come to think of it, I think that Vista was going to REQUIRE me to remove 2017 before installing the 2015, and so perhaps I never proceeded, because who knows how it would have affected other programs on my computer.

But I will go through the process again, to be sure.

@Sunny2019, I'm still using a Vista PC, but when Firefox also notified that no further updates were possible I downloaded a Linux ISO (Cinnamon) and revitalized this old hardware. I installed it side by side and can access the old files as if they were in another drive. I can use Firefox 75.0 and for my few needs this is enough. Too bad for MuseScore 3.2.3 seems like a last resort.

Yes, it is a very controversial subject to discuss whether or not to upgrade an OS. There is a trade-off, because some of your programs no longer work on the new OS, and drivers for your scanner and printer, but then other programs do work. Also, installing a new OS and all the programs formerly installed on the previous OS, and re-adjusting all the settings, can take many weeks of precious time away from other important things in life.

I would rather try to run it direcly from the hard drive, if that is possible.

I have installed Oracle VM Virtual Box Manager v.5.2. Is this a sort of platform onto which I must still install Ubuntu separately, or is Ubuntu already included in it? I am stuck.

If I must download Ubuntu separately and install it onto the Virtual Box Manager, how do I do that, and which version will work on this Vista installation?

VM is the one who recommended frfancha ( )
I was just suggesting to make a DVD executable. After extract nothing would be modified on your Vista.
Download the ISO, save it; Right button->masterize disk image;
Insert the burned DVD, restart the pc and follow the instructions.
At the end of the session you will extract the DVD.
You will find many simple instructions on the net, eg.

Running Windows in an unsupported version (i.e. anything other then 8.1 or 10, and possibly 7 Enterprise) and connecting those to the internet is a dangerous as those don't receive any security updates anymore and there are security leaks and corresponding exploits out there in the wild . There's nothing controversial about that, just don't.
Oftentimes it is possible to upgrade from one version to the other, without loosing installed programs and files, but sometimes it is just better and easier to install afresh from scratch. Also there is not updating from a 32bit Windows to a 64bit one and the latter is needed in order to make use of more then 4GB RAM. And if you don't have an SSD yet, this is the chance.

Windows 10 does occasionally update, I wouldn't call it frequent. You can always turn it off if you prefer to take your chances and stay on older versions. I prefer having bugs fixed for me, so I typically leave it on except on one machine where there just isn't enough room. Windows does send telemetry data as do most programs by default, but that's not the same as "personal information".
