@BLAyEnnI don't personally know how long it will be before the Origin-team will fix the underlying bug, but in the mean time you can use this workaround to fix the problem and play the CNC-games: 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 The Origin-downgrade workaround was adviced in the beginning of this topic, but the workaround above is a bit simpler, fixes the problem and allows Origin to be updated. I would thus advice to update Origin and then apply the above workaround.
Origin (but also platforms like Steam) need to be updated to keep the online store, DRM etc. working correctly and fix some bugs. Yes, EA could have maybe have rollbacked to a previous version of Origin, but that would have probably erased progress on other bug fixes. So, it is not that EA/Origin doesn't care, they are just still working on the fix according to @EA_Kent It has been around 4 weeks now since this bug started to appear on this forum, so I hope the fix for you guys comes soon 🙂
The Steam-versions are indeed very expensive, even more expensive than The Ultimate Collection on Origin during Steam-sale. The disc-versions won't work on Windows 10 as it doesn't support its crappy SecuRom DRM anymore (Windows 7 and 8 also don't support it anymore, but it can be re-activated there.) So, buying the disk-versions would be useless, especially in the future...
Edit: Btw, I remembered you already "complained" about this bug, but especially Origin earlier this week. See my reaction to that here: 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/8777592/highlight/true#M17729
