Illustator Installation Error 145

[moezarella]

Hello everyone, 
I have a case, my Illustator can't do update because of the same code. After over and over failed updates, i decided to uninstall it, restart my laptop and install it. 
But appararantely, the same code came and here is the log :

Exit Code: 145
-------------------------------------- Summary --------------------------------------
 - 2 fatal error(s), 0 error(s), 1 warnings(s) 

FATAL: Error (Code = 145) executing in command 'MoveFileCommand' for package: 'CoreSync-mul', version:6.6.3.1
FATAL: Error occurred in install of package (Name: CoreSync-mul Version: 6.6.3.1). Error code: '145'
WARN: Destination path is file or already used "/Applications/Utilities/Adobe Sync/CoreSync/Core Sync.app/Contents/Frameworks/AdobeCrashReporter.framework/Versions/A/Adobe Crash Reporter.app/Contents/Resources/de.lproj/MainMenu.nib/classes.nib"
-------------------------------------------------------------------------------------

Following the folder path  /Applications/Utilities/Adobe Sync/CoreSync/Core Sync.app/
it just ends there, because the Core Sync app can't be opened 😕

is there anything i can do now? i really wanted to try Illustator new update. 

Thank you.
