Launcher VC Redist x64 UAC Prompt

Hey all. Just posting this here in case it helps someone else.

If your PC is like mine, every time you open the ESO launcher, you get a UAC prompt about vcredist_x64.exe or vcredist_x64_2015.exe.

After some digging, I discovered that this is usually caused because you have a newer version of Visual C++ 2017 redistributable installed on your machine, so it causes the dependency check to fail.

The way I was able to fix it was to follow these steps:

1. Download both x86 and x64 versions of the latest Visual C++ 2015-2019 Redistributable from Microsoft
2. Rename the downloaded x64 version to vcredist_x64_2015.exe
3. Rename the downloaded x86 version to vcredist_x86_2015.exe
4. Install both new downloaded packages and then reboot the PC when prompted. They will automatically replace any 2015, 2017, 2018 or 2019 versions of Visual C++ in your Apps and Features / Programs and Features control panel.
5. In your Zenimax Online Launcher install location (default C:\Program Files (x86)\Zenimax Online\Launcher), create a new folder named "bak"
6. In your Zenimax Online Launcher install folder, move vcredist_x64_2015.exe and vcredist_x86_2015.exe that were bundled with the launcher into the new "bak" folder
7. Move your downloads that you installed in step 4 into your Zenimax Online Launcher install folder.

Now, the next time you start your launcher, you shouldn't get any UAC prompt, because the version check will pass.

I hope this helps someone else.
