2.While viewing video cutscenes in between levels, it either goes silent or repeats the same phrase at some point for a short time

* If using Realtek High Definition Audio, Soundmax HD Audio, or nForce Audio,
you may experience sound anomalies.

To work around the problem, reduce the Hardware acceleration slider to ‘Basic’
in the Control Panel->Sounds and Audio Devices->Audio tab->Advanced->Performance
tab.

3.I click to play and I get this message GAME.LOST CONNECTION.RESUME

Maybe you got a piracy edition, this whole game is protected, soyou can only access the main menu. If this is reallya problem, let’s wait for ubisoft hotfix

Missing menu options and in game textures

If you are running into the issues with missing menu text, menu items or in game textures, try disabling Catalyst AI in Catalyst control panel. You need to do this in all applicable places (i.e. under the AI tab as well as All tab in CCC).

My screen resolution is not supported. What’s up?

This is not a technical fix but more like a UI issue. If you try to change the video resolution in Splinter Cell : Conviction, sometimes you may find the resolution that matches your display is missing from the list (for example some widescreen res). You might not notice it but you can actually scroll down the list of resolutions.

Cannot display video mode error – game starts up in a resolution unsupported by the monitor

If you get this error, you might have to manually edit the game configuration file and set a resolution compatible with your monitor. There is a detailed forum thread on UBISoft forums on how to do this – you may access it from here.

scc.exe stopped working error when trying to launch the game

Sometimes, the game might hang at launch when it tries to auto detect system components. If this happens, you can bypass the auto detection process, launch the game and manually adjust optimal settings yourself. Navigate to your game’s installation directory and rename the file systemdetection.dll to something else. Now launch the game – it will throw an error message but the game should launch instead of hanging.

some updated will be added later
