How to fix "failed to send request" error for Renegade, Tiberium Wars, Kane's Wrath, RA3 and Uprising when wishing to play offline

[himzokevric]

The recent Steam Workshop patch for the Command and Conquer collection causes the named titles to generate a "failed to send request" error on launching offline. Each of these is fixed a certain way.

For Renegade, simply create a shortcut of Game.exe from the main game folder and it will work.

Tiberium Wars, KW, RA3, and Uprising all have Skudef files in their respective game folders with variable numbers. These are the patch versions of each game. For example, Tiberium Wars has CNC3_english_1.10.SkuDef as its latest version. Rename it to whatever you desire and the game will be able to launch offline. This works because the version number of Tiberium Wars is 1.09.

For Kane's Wrath and the Red Alert 3 titles, do the same thing, rename the highest skudef number to whatever you want and the games will launch offline. It may be wise to not delete those renamed skudef files in case they are required for online play, and you may need to rename them back to their original name for this purpose.

For Generals and Zero Hour, a computer restart may fix the issue.
