Potential FIX for Forza Horizon 4 not launching on Steam

This guide is aimed at those who had their Forza Horizon 4 not launching on Steam at all.

If you didn't use BitDefender or didn't have non-latin characters in your username and the game still doesn't launch for you completely without any error box - you might want to try this as a potential FIX.

A keen eye might notice that official troubleshooting guide from Forza Support Team mentions reinstalling Microsoft Visual C++ programs, but they only reinstall the most recent version, which is not enough to fix the issue.

1. Press the Windows Key + R, type appwiz.cpl and then press Enter

2. This will open Programs and Features. Search for "Visual C++" to find all Microsoft Visual C++ Redistributables

3. Uninstall each version / architecture of Microsoft Visual C++ Redistributable one by one.

This my seem like a lot, but they actually uninstall pretty quickly (your mileage may vary though)

4. Download ALL packages of VCRedist Visual Studio C++ runtimes from here

https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/

This is the key part of the guide, because it seems that Forza Horizon 4 actually needs one of the older versions of VCRedist Visual Studio C++ runtime, possibly even an x86 one.

5. Extract contents of Visual-C-Runtimes-All-in-One-Mar-2021.zip

6. Run install_all.bat as administrator to install all Visual C++ programs with a single action

Wait for the installation process to complete.

7. Launch the game in Steam

Your PC might need a restart, which wasn't required in my case.

If your error matches what's described in the guide info box and this FIX didn't work for you, please let me know.

I sincerely hope this guide works for you.

A minor addition - if you have MacType installed, disabling it while running Forza helped me after a certain update.

IDK how far this fix the crash of FH4. but if still not work, then reinstall all MSVC++ didn't do good. otherwise, downgrade to old version of Nvidia driver

Thanks, this worked. Pretty sure this was caused by me trying to update my vc runtimes for another game.

After hours of troubleshooting, closing Riot Vanguard finally let me launch the game. Looks like Valorant is a virus after all.
