The Witcher 3 Won't Launch on Steam?!?

Hello.
 
It's the weekend, and I decided to play The Witcher 3, a game I enjoyed a long time ago.
After reinstalling it from Steam and clicking the Play button, it changed to a Stop button, indicating that it was about to launch. However, within seconds, the game didn't start and the button reverted back to Play. There were no error messages or pop-up alerts. (See the video below)

Before my anger escalated, I quickly searched for a solution. To figure out what was going on, I had to find the Witcher's executable folder and double-click it to see the error.
Since I'm using a Windows 64x system, I found that The Witcher was installed in the following path.
C:\Program Files (x86)\Steam\steamapps\common\The Witcher 3\bin\x64 containing wither3.exe  

The error message showed that the file VCOMP11.DLL was missing, causing the issue.
Apparently, installing the Visual C++ Redistributable for Visual Studio 2012 Update 4 would fix it.
You can download and install the VSU4\vcredist_x86.exe file from the link below if you are using a 64-bit system after selecting Korean.

Thinking back, I realized that I had removed/changed some programs while cleaning up my computer. If you look at the installed programs below, you'll see multiple files named Microsoft Visual C++ 2008, 2012, 2015-2019, etc. These types of files are often required for running games and other programs. There were about 20 of them, and I remember deleting them all. If you're experiencing the same issue, you might have also messed with these files.

Anyway, it's all fixed now, and I can finally explore the world of The Witcher again. I'm starting with the Blood and Wine DLC, known for its beautiful scenery. After defeating a monstrous giant, I feel refreshed...
Hope you all have a great weekend.
