Wing ide start-up crash

edit

Ive been using 5.1.12-1 ver. wing ide. It worked just fine but when I tried out 6.0.4-1 ver on my computer, it crashes everytime I run the program.I can't find a way to fix this problem. I tried to redownload and reinstall the program but didnt work.

"C:\Users\user name\AppData\Roaming\wing 101 6\ide" file says the following everytime i run the program

I have tried the exe file at C:\Program Files (x86)\Wing IDE Personal 5.1\bin\console_wing and the cmd (im not sure) said something like   

wingide - 2017/04/05 22:13:56 - ('Inspect failed', UnicodeDecodeError('utf8', 'c:\\users\\\xbd\xc5\xb0\xe6\xc8\xaf\\appdata\\local\\temp\\tmpdu3rua.py', 9, 10, 'invalid start byte'), None, '')

So i know that it's crashing with some kinda error message but I don't know what the problem is and how to fix this especially when the older version worked just fine.

thanks for reading and helping me :)
