api ms win core synch l1 2 0 dll Problem

So I tried to install discord and this message came out http://prntscr.com/h32p71 and i googled that dll and downloaded it but when I tried to move it in my system32 folder it said that I already have that dll file, I really don't know what to do and I would be happy if you help me(That problem started when i downgraded from win10 to win7).

Moved from:(Windows / Windows 7 / Performance & system failures)

Hi Amer,

A missing or corrupted file can be the cause for this error. To help us determine the appropriate troubleshooting steps that can resolve your concern, we would like to ask the following questions:

  • What is the name of the program that you want to install?
  • What is the exact file name of the DLL that you want to move in the system32 folder?

We look forward to your response.

I have the same problem trying to load a printer. Tried Canon. Also have tried to load a Quicken program and get the error message.

I think there are lots of different kinds of Canon printers and lots of different Quicken programs.

I would start with these ideas, restart your system when you are done installing and see how things look:

That file is not included in any Windows installation, Service Pack or update.

The problem is that the developers have used some version of C++ to create their programs and the programs require some runtime files (Dynamic Linked Libraries) to be present in order to install/run and the developers do not include those files with their installation (why not?) and the websites for the programs often do not list the prerequisites and requirements of what you need to have installed for their programs to work.

They think that since the program installs and works fine on their system (because they have all the requirements) that the install will work fine on every other system in the world too.  Short sighted thinking.

These files are not part of or included in a regular Windows installation so no amount of Safe Mode, Clean Boot or sfc /scannow is going to help you or make the missing file magically appear (sorry Microsoft engaged Support Engineer alleged "experts").

What you need to do is install the Visual C++ Runtime files and I would start with the 2015 version which you can download from this link:

https://www.microsoft.com/en-us/download/details.aspx?id=48145

Then download/launch/run/install the right architecture (bitness) for your system:

You should also install this KB Update if it is not already installed (you can't install it twice):

https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

After the installation you shouldn't have to restart your system but do it anyway then see how your install works.

FYI:

Over time you may find that you may need several C++ runtimes installed as you can see here:

Having several versions of C++ Redistributable is normal... depending on what third party programs you might have installed.
