What I hadn't anticipated in the install, that it will require at least twice as much disk space on my C:\ drive for downloading, then patching, and finally deleting the temporary files. It would have been really very, very nice if the patcher had checked the required amount of disk space just before starting the download.
At the moment I am running the repair tool after the patcher complained about errors during patching. Fun thing is that it marked some "pak__new" files for removal and is now apparently downloading older ones...
Now I could actually press play on the patcher although the servers are showing maintenance. Hmmm, I really hope I won't have to reinstall. I may update this post once I am back in the game. Let's hope.
Update: Checking the patcher and the repair log, it only redownloaded a couple of pak files, where it failed to apply the patch in the first place (atlas, crusader, gameassets .pak files and a few more). It seems during installation it generates a "new" file for the downloaded content, deletes the old file and renames the new file to the current one. So the "new" files apparently are just remnants of the previously failed patch/renaming process. I rerun the repair tool and it checked out fine. Now I am just waiting on maintenance to finish.
