Error 0xc000007b. Already tried several things
Hi! I just installed unity lastest version. When I try to open the program that error pops up. Unity hub opens normally, but I can't start a new project. My OS is 64 bits, I tried replacing some DLLs (As I saw in many forums) but it didn't work. Unity Editor 32 bit versions work fine (Tried 5.6.7f1 32 bits). I never used Unity before.
I'm one step away from reinstaling Windows or something

Hi, try to Reinstall .NET framework Windows 10 uses .NET Framework 4.5 but didn’t include version 3.5 to make it compatible with older apps. This can be the root of the ‘The application was unable to start correctly (0xc000007b)’ error. Click “Start” button to select Control Panel and click Programs and Features. Click “Turn Windows features on or off” item on the left panel. The “Windows Features” window pops up. Find and click .NET Framework 3.5 and press OK. Then it will start downloading and installation. Restart the computer and check whether this error is fixed. Step by step fix with other working methods on 0xc000007b

From https://answers.unity.com/questions/1158383/error-0xc000007b-when-starting-unityexe.html
To resolve replace mfc100.dll, mfc100u.dll, msvcr100.dll, msvcp100.dll files at your C:\Windows\System32 folder with 64 bit versions.
