Slice of Venture: A New Start

Good evening,
can I ask how to start the game? After downloading and extracting the game I tried to start the BGI.exe, but nothing happened. Since I only know games which have a game.exe I thought this BGI would be the same.
 
After trying the BGI, I tried the BHVC.exe, which saif, that there is an error in the sysprg.arc. Does anyone know how to fix this?
I tried to set my pcs locale to japan, but that didn't change anything either.
 
I hope this is the right place for this topic. If not, I'm very sorry.
 

While the newbies are desperately trying to get used to their relaxed life at university, our MC is already at a point in his studying career where he is thinking about topics for his bachelor thesis. He has been studying for two years straight, and by now, there is little that can throw him off. Each new day is more or less the same.

His simple situation suddenly changes when the people around him start acting weird. He has a hard time explaining their actions, but just because MC didn’t see these changes coming doesn’t mean they are bad.
Right around the beginning of his third year, our MC experiences a week full of opportunities.

I always get this message. Help
