I'll extract the game, but I get two errors saying:

"Can not open file: access is denied C:\Users\Andrea\Downloads\Signed_and_Sealed_With_a_Kiss-market\Signed_and_Sealed_With_a_Kiss.exe" and "C:\Users\Andrea\Downloads\Signed_and_Sealed_With_a_Kiss-market\lib\windows-i686\Signed_and_Sealed_With_a_Kiss.exe."

I had just updated Windows 10 yesterday,  in case that could be the problem, but all my other .exe files still work. I also completely deleted the other file from before the update without backing it up. I'm not sure if it's necessary to add, but the icon to the .exe file is a blank page.

Hi,

We can confirm that the game works on Windows 10 (it's the OS the game was mainly tested on). It sounds like you aren't running the game with the correct system permissions or perhaps your download was corrupted.

It's working now. Thank you.
