I bought FO3 back when it was first released, before the GOTY editions existed, so all my DLC is either from Steam or GFWL. However what's odd is that not only does the installer not detect the DLC (despite being in the proper place), it doesn't detect my Steam-based FO3 installation at ALL. I of course verified the files through Steam and even deleted and re-downloaded them. My FO3 Steam appid is 22300 and I'd be happy to provide the MD5, CRC, or whatever validation hashes you may use. My only thought on why this may be occurring is that I have SteamLibaries on multiple HDDs and overall Steam is not installed under "Program Files (x86)" like it defaults to. Thanks for any help in advance. Below is the log entry from the installer:

Edit: Whoops, forgot my OS info! It's Windows 10 Pro 64-bit. The installer is being run as admin. There appear to be no file permission or UAC issues in ProcMon.
Edit 2: Well I did a whole bunch of nothing and now it decides to work. Huh. Nevermind? You can delete this thread.
