Recently, my Minecraft Launcher won't load any installation other than an Optifine 1.14.4 installation that I use frequently. To solve this, I uninstalled the launcher and tried to reinstall it using the MinecraftInstaller.msi but whenever it finishes installing the launcher, it appears blank (the white paper with a fold on the top-right corner). When I try to open it, a window pops up with the following message:

Couldn't load launcher core from C:\Program Files (x86)\Minecraft

Launcher\game\launcher.dll: LoadErrorNotPresent

And then after I click "OK" another window pops up, saying:

Unable to start the Minecraft Runtime Environment. This is most likely cause by a corruption. Please try to reinstall Minecraft.

I followed that advice and reinstalled Minecraft multiple times. The entire process just starts over, and I'm starting to feel hopeless. Before I buy Minecraft again, does anyone have a solution to this?

HUGE thank you to anyone who tries to help me fix this! Even if your solution doesn't work, I am infinitely grateful for you at least trying.
