Actually, if you look at the message that appears below, the solution has also been given. Just 3 steps, namely :
- Click Start – Control Panel – Clock, Language, and Region.
- Click Region and Language, select Indonesian (Indonesia) under Format and then click OK.
- Restart the laptop/PC and run the eSPT program again.
For some users, they may have finished with the solutions above and may still experience problems like me. I checked again, the above step should be correct, but after re-checking again, it turns out that all accounts on the laptop / PC, must be set up as in the steps above. So if there are administrator and user accounts, everything must be set to Indonesia.
Good luck and have a great day.
