Hi, and welcome.
Sorry, but that doesn't make sense...
Here's the download link to the official MPC page:
https://mpc-hc.org/downloads/
Just in case you're getting it from somewhere else, make sure you always get it from the official site.
Anyway if the problem persists, try out MPDN:

Assuming SVP and all its components are installed correctly, follow the instructions below:
Scroll down the first post and look for these three files; install them in the following order:
1. "zachsaw.com Software Certificate"
2. "Media Player .NET (MPDN) Installer - x86 Edition"
3. "MPDN Extensions Installer"
Once you're done with that, run MPDN... And EDIT the following settings;
Click on View, then open Options.
On the left panel, click on Video which is under DirectShow...
Now under Available Filters* scroll down until you see "ffdshow raw video filter", use the arrow keys between the panels, to move "ffdshow raw video filter" to the right side so it is under Selected Filters.
Click APPLY, then Click OK.
While SVP is running in the background, now open a video of your choice with MPDN.
If everything is working fine then we can figure out why your MPC is not working, otherwise if MPDN doesn't work too, then I'm not sure what is going on unless you provide further details.
