Same. When I go to Steam Apps and locate the file it is just empty .txt files....boo....

Solution:

To resolve the issue of a missing executable error when trying to play Stardew Valley after just installing the game, you can follow these steps:

Verify Game Files:

Open Steam and go to your Library.
Right-click on Stardew Valley and select “Properties.”
Go to the “Local Files” tab and click on “Verify Integrity of Game Files.”
Steam will then check for any missing or corrupted files and redownload them if necessary.
Reinstall the Game:

If verifying the game files does not solve the issue, you can try uninstalling Stardew Valley and then reinstalling it.
Right-click on Stardew Valley in your Library and select “Uninstall.”
Once uninstalled, download and install the game again from the Steam store.
Restart Steam:

Sometimes, simply restarting Steam can help resolve various issues.
Close Steam completely and reopen it to see if the problem persists.
Check Antivirus Software:

Your antivirus software may be blocking or removing essential game files. Make sure that your antivirus is not interfering with the game installation process.
Run Steam as Administrator:

Running Steam with administrator privileges can sometimes resolve permission-related issues that cause missing executable errors.
Right-click on the Steam shortcut and select “Run as Administrator.”
Update Graphics Drivers:

Outdated or corrupt graphics drivers can also cause issues with launching games. Make sure your graphics drivers are up to date.
Contact Support:

If none of the above solutions work, you may need to contact Steam support for further assistance with resolving the missing executable error.
