i hava same error with you this is updatelogtxt s content : ERROR(6001): An exception has occured while updating. Report to Nemesis' author immediately | Message: 在多字节的目标代码页中，没有此 Unicode 字符可以映射到的字符。 and i cant switch language that leads to flash back

I have the same error but in full english, maybe its caused by our system locale? only happen with 0.84 beta

ERROR(6001): An exception has occured while updating. Report to Nemesis' author immediately
Message: No mapping for the Unicode character exists in the target multi-byte code page.

Edit: use locale emulator to emulate english, then use virtual explorer to launch nemesis with locale emulator(english), that should fix it
