Re: CAW won't start on Win10
@Vgrace573 I have no idea why you had to fiddle with your old computer in order to play games, TS3 or other; Windows 10 usually runs TS3 just fine. But the first question is whether you can run TS3 itself, not CAW. If not, the issue may be your antivirus/firewall (try disabling it temporarily to test), or it may be a missing or corrupt file that the game needs to work.
So please let me know whether you can now play TS3, and if not, whether you get any errors, and which ones, and where in the process it crashes.
If the game itself does run, but CAW doesn't, please make sure you're using the correct version of CAW. There are separate downloads for 1.67 (disc/Steam) and 1.69 (Origin) installs. I haven't heard anything about launching CAW through Origin, but you can always try signing into Origin first and then opening CAW.
Please make sure to disable OneDrive while you're testing. I don't know that it causes issues with CAW specifically, but it can be a real problem with TS3 itself, as OneDrive tries to sync with or upload your local Documents folder. If you use it for other purposes, you can fiddle with the settings to prevent it from doing anything automatically, but while you're testing, just go into Settings and turn it off entirely.
Finally, whether this is a CAW issue or still extends to TS3, please run a dxdiag and attach the results to a post here. This will cover a number of potential issues, and at the end, it will list the last 10 errors, usually including the faulting file.

I know this is a lot, but there are so many ways TS3 can go wrong, and CAW is often an additional headache. So it's difficult to troubleshoot without more information.
