Well, in response to your suggestions, it probably would have helped giving spec' huh?
I am using the Japanese Locale Region, on a Win8 Laptop (Unsure if this could cause issues).
I have previously tried having it running compatibility mode for Win7 and then running as Admin and that didn't work either.
I've already tried CCCP earlier but i installed it again just on the off chance i missed something, but it was still doing it then.
I've had a look in the Regedit and the application does follow the path of;
Computer\HKEY_CURRENT_USER\Software\propeller\*Hiragana that i can't copy/paste*
and the "instpath" does follow it correctly, referencing "C:\Ayakashibito"" as the Value Data.
I got the original file from Fuwanovel a few days back, but after trying various things to fix this issues, tried re-downloading the whole thing again and just shifting over my Saves and that failed as well.
As per the link you included as well, as mentioned above, the instpath is English with no Japanese characters in it. The actual directory wasn't though so i tried renaming that and that just threw out the settings that the .Bat had created, and when i re-ran it, it just created a new directory entry with the same characters i had renamed, also tried using the Japanese characters in the actual filepath of explorer in case...still no dice. :'(
Thanks for the suggestions though.
