Actually, if you see the message that appears below, a solution has also been given. Just 3 steps, namely :

1. Click Start – Control Panel – Clock, Language, and Region.

2. Click Region and Language, select Indonesian (Indonesia) under Format then click OK.

3. Restart the laptop / PC and run the program again.

For some users, maybe you have finished with the solution above and maybe you still have problems like me. I checked again that the steps above should be correct, but after checking and checking, it turns out that all accounts on the laptop / PC, must be set as the steps above. So if there are administrator and user accounts, everything must be set to Indonesia.

Good luck and have a nice day.
