I can't get the update program to work for Touhou Skydrifters

[zferolie]

I am trying to update my game, since I guess you need to to play Campain. It installs an updater, and when I run it it starts to, but then this message happens(I google translated it)

[ Error ] failed to rename the old version of the file . You may still have the same name for the backup file .An error occurred during the application of the differential file .The in the middle of working files it's back to the original ...It was returned to the original in the middle of working files

I am not sure what I am doing wrong, I am just saying Yes to every prompt. Anyone having this issue or know how to fix it? I can play the game in 1.000 but I only have thevs option. Wanted to stream the game...

I guess no one here has this game?

I cannot translate this since it won't let me copy.
