My error was using IPA.exe when modding the game. My fix was remove the game and clean the registry issues by using IPA.exe on StudioNero.exe, in the end it was a reg issue. with new install all is well.
use your windows OS, install the language package japan as main language and with your spoken language as secondary. then install your game. It works for me.
Hope this helps.
I had the same problem so I converted the flash exe file to a swf file. What this does is removes any blocks that stop you from running the program. I used Flash player Pro to do this. just goto tools menu under convert exe to swf, then select the exe file and click convert.hope this helps you.
I think this is a Mod for Skyrim as the title states... if so you will need to place files in your data folder. Best use a "Mod manager" to install the mod then run Loot or Boss to get the load order corrected. then run Skyrim. This download may have a read me file to help.
