Hello habib shuvo,
You can be 95% sure that there is no fault in your operating system. So, the problem cannot be solved by reinstalling the operating system. This problem can occur due to the following reasons.
1) Sometimes, games are divided into multiple RAR files i.e. the game works only if all the related RAR files are present.
2) Sometimes, the RAR files may be infected with viruses. Then, the message 'RAR file is corrupted' will be shown.
3) Sometimes, the problem may be due to the improper installation of software i.e. WinRar, WinZip etc,. To check whether there is a problem in the software, try to open the same RAR file with another such software. If the problem doesn't occur, you can be sure that there is a fault in your software.
Also, try to open the same RAR file in another computer and see whether it works or not. If it doesn't work, you can be sure that there is a fault in the RAR file. And don't forget to scan the RAR file using an antivirus software before/after your problem is solved.
Hope this answer helps to solve your problem.
