Can't launch Minecraft

When I open the Minecraft Launcher and press play, an error message pops up that says "Loadlibrary failed with error 87: The parameter is incorrect." and does not let me start Minecraft. I have uninstalled BitDefender since it's incompatible with Minecraft, and uninstalled and reinstalled Minecraft, but it didn't work. It's extremely frustrating since I don't know what the problem is. I love Minecraft and just want to play it.
