I had the same issue and was able to resolve it - the patch wizard assumes that your game data is in a certain location, but I have my steam games on a second hard drive, so the wizard was trying to change files on Local Disk (C:) when it should have been changing the files on (D:). Maybe other people who are having the same issues also have their Steam files somewhere atypical?

Yeah, I have mine installed at E:\Steam and it isn't finding it.
From what I'm seeing on stackoverflow, you'll want to first get the Steam install location from the registry:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Valve\Steam\InstallPath
Then, you can get the library paths from:
\Steam\SteamApps\libraryfolders.vdf
There's a sample python script here (needs to be modified to use the Steam InstallPath from the registry):

the libraryfolders.vdf looks like a JSON that can hold multiple library configs. For example on my system:
"libraryfolders" { "0" { "path" "E:\\Steam" "label" "" "contentid" "xxxxxxxx" "totalsize" "0" "update_clean_bytes_tally" "2147829949" "time_last_update_verified" "1739270362" "apps" { "228980" "423466214" "281990" "22729289796" "289070" "29135479543" "321060" "642708774" "867210" "2274391871" "908070" "490324899" "990080" "76500141990" "1203620" "35390308344" "1268590" "6750084266" "1383680" "583123577" "1393370" "4328293065" "1827650" "640540130" "1958220" "11647855498" "2026000" "3291908994" "2135150" "0" "2407360" "15027504367" "2594920" "956356683" "3065170" "24976820946" "3107230" "12519113988" } } }
Since there could be multiple libraries, you might want to also confirm that the appID for Star Knightess Aura ("1827650") is also in the "apps" section for the library (if more than just "0" in the root element of "libraryfolders").
