Hi, if you've already tried the tips I mentioned in the comments, such as re-extracting the game, disabling 'Run as administrator', but your game still crashes, here are a few other suggestions you can try:
1. If you have other versions of CS 1.6, uninstall it fully with REVO UNINSTALLER and then try re-extracting the c-valorant.
2. Adding 'hl.exe' to Data Execution Program (DEP). (Type sysdm.cpl in the run command. Advanced > Perfomance > Settings > Data Execution Program > All Programs > Add > select hl.exe
REGEDIT FIX
3. Win + r. Type 'regedit'. Go to :
HKEY_CURRENT_USER > Software > Valve > Half-Life > Settings.
> Click on 'ScreenHeight' > Decimal (Always use decimal while changing the value) > 768
> Click on 'ScreenWidth' > Decimal > 1024
If that also does not fixes the crash then :
(TRY ONE TWEAK AT A TIME)
> 'EngineD3D' > 1 (It will run the game in D3D Video Mode, you might get a bit lower fps.)
> 'ScreenWindowed' > 1 (Optional)
> 'ScreenBPP' > Decimal > 16 (Not So Recommended)
> 'hdmodels' > 0
---------------------------------------------------------
> 'CrashInitializingVideoMode' > 1 (It will run the game in software mode, you will get visual glitches, try it if the game still crashes after you did all the 3 solutions i mentioned. Not so recommended.)
