Re: The Command and Conquer Ultimate Collection.

@SIKOKIS86That is caused by a current known bug since a recent Origin-update. Which are unrelated to the problems of @Nightmarelsx See here for a workaround: https://answers.ea.com/t5/C-C-The-Ultimate-Collection/Can-t-launch-C-amp-C-The-Ultimate-Collection-games-after-24-01/m-p/8716040#M17504

@Nightmarelsx
Renegade: Maybe try CnCNet as an alternative to XWIS: https://cncnet.org/renegade Never tried it, but I heard great things about it. Also apply the Tiberian Technologies patch, which apparently fixes many issues. See: https://answers.ea.com/t5/C-C-The-Ultimate-Collection/Command-and-Conquer-Red-Alert/m-p/8795940/highlight/true#M17770

Generals:
See: https://www.pcgamingwiki.com/wiki/Command_%26_Conquer:_Generals#.22Technical_Difficulties.22_error.2FSerious_Error Please follow all the steps under both ""Technical Difficulties" error/Serious Error" and "DirectX 8.1 error (Windows)". One of those solutions should fix the problem, especially the steps under "Create or edit Options.ini" I think.

Tiberium Sun:

Please report back to let us know if any of this worked 🙂

Edit: Shame to me, saw only just now that the original post wasn't recent, but from 2013 haha. Really strange that nobody answered the original post 7 years ago.... Well, hopefully I could help others with it. @SIKOKIS86 can at least probably fix his issue with the provided workaround 🙂
