Thank you for answer, Mike.
First, my keyboard language is set to english. Keyboard language set properly, sure.
Secondly, system is Windows 10 64bit on ASUS GL502VS-FY028T 90NB0DD1-M00990 notebook.
Absolutely right, at first I've checked the Shift key recognition on plugging in a USB keyboard. No effect.
And input passphrase ("Show keystroke" mode on) on set up software screen, it's clear on the display.
My previous system is Windows 8 64bit on other notebook, and I use the same passphrase with Shift key recognition SYMC DRIVE ENCRYPTION 10.3.2 MP13 (Order #[Information redacted]).
Sure, I'll try again with another USB keyboard.
Thank you for help in resolving technical case number[Information redacted].
I'm waiting for instructions from you for resolving this case and using my system.
