Outdated or incompatible drivers
The drivers are software components that allow your hardware devices, such as your graphics card, sound card, or mouse, to communicate with your operating system and applications. If your drivers are outdated or incompatible with your system or the game, they may cause performance issues or errors.
Conflicting programs or antivirus software

Fortunately, there are some simple solutions that you can try to fix the error message "Unable to execute command left4dead2 exe steam2" and enjoy the game without any hassle. Here are some of them:
Verify the integrity of game files

Open Steam and go to your library.
Right-click on Left 4 Dead 2 and select Properties.
Go to the Local Files tab and click on Verify Integrity of Game Files.
Wait for the process to complete and then restart Steam.
Try launching Left 4 Dead 2 again and see if the error is gone.
Update your drivers
The next thing you should do is to make sure that your drivers are up to date and compatible with your system and the game. You can do this by using a driver updater tool that automatically scans your system for outdated or missing drivers and installs them for you. Alternatively, you can manually update your drivers by visiting the manufacturer's website and downloading the latest versions for your devices. Here's how:
Press Windows + R keys to open Run dialog box.
Type devmgmt.msc and press Enter to open Device Manager.
Expand the categories of devices that you want to update, such as Display adapters, Sound, video and game controllers, or Mice and other pointing devices.
Right-click on each device and select Update driver.
Select Search automatically for updated driver software and follow the on-screen instructions.
Repeat this for all devices that you want to update.
Restart your computer after updating your drivers.
Try launching Left 4 Dead 2 again and see if the error is gone.
Run the game as administrator
Sometimes, the game may need administrative privileges to access certain files or resources that it needs to run. If you don't run the game as administrator, it may encounter errors or crashes. To fix this, you can try running the game as administrator by following these steps:
Navigate to the folder where Left 4 Dead 2 is installed on your computer. The default location is C:\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2.
Right-click on left4dead2.exe file and select Properties.

Disable or whitelist your antivirus software
Finally, you should check if your antivirus software is blocking or deleting any files that the game needs to run.

To fix this, you can try disabling your antivirus software temporarily or adding the game folder to its whitelist or exceptions list. Here's how:
Open your antivirus software and look for a way to disable it temporarily. Usually, you can find this option in the settings or by right-clicking on the antivirus icon in the system tray.
Alternatively, you can look for a way to add the game folder to the whitelist or exceptions list of your antivirus software. This will allow the game files to run without being blocked or deleted by the antivirus.
