Dear colleagues,

I have the square only instead of Celcius degree sign " ° ". I know, that normally I should go in TIA to Online => HMI Device maintenance => Options and add there Chinese_fonts from left to the right area. But whatever I have tried (downloaded, copied from good working computer..) with the corresponding file, it always gave me this error message (not exactly):

"The signature of the language file is wrong or file is corrupted".

Colleague's computer performs this action without any problem.

Please help to understand what to do to implement this Chinese_fonts into that HMI. What is wrong with my PC?
