Dear Suthriak-san
Can I assume you have removed MySATOPrinter.dll from project once and re-added into the project?
We are not working this week because of Chinese New Year holiday.
It will be really great if your user can test the build by Ken-san first.
If the build is working fine for your users, you can implement the version for time being.
In fact we are quite packed now because of multiple projects handling. I would suggest we will work on the development environment in few weeks time.
