System Restore is a Microsoft® Windows® tool designed to protect and repair the computer software. System Restore takes a “snapshot” of the some system files and the Windows registry and saves them as Restore Points. When an install failure or data corruption occurs, System Restore can return a system to working condition without you having to reinstall the operating system. It repairs the Windows environment by reverting to the files and settings that were saved in the restore point.

  • Select the Start button, then type control panel in the search box next to the Start button on the taskbar and select Control Panel (Desktop app) from the results.

This means that if your system was working fine last month and you put the date from last month to restore your system, everything after the chosen date will delete. All installations, applications, passwords, saved data, DLLs, EXE files, and everything will be removed right away.

Unity’s Bug Reporter tool collects various information about your system, such as driver versions, log files, etc. that helps them to identify the problem. If the player crashes, it normally creates a “crashes” directory next to its .exe file that contains a crash.dmp file. It proved useful to attach this crash.dmp and log file to the bug-report as well.

Using the bug-reporter is an important step, because it makes sure the report is in Unity Technologies bug-tracking pipeline. Using the forum is often used to add attention to an existing issue, but does not replace submitting a bug-report.  It is from advantage to attach a project to the bug-report that UT can use to reproduce the issue and test their fix against, this is especially important for crash-bugs.  The easier an issue can be reproduced by QA, the more likely it is to be forwarded to a developer, who might or might not work on a bug fix for that at some point.

After you submitted the bug-report, you receive a confirmation email with a Case number. UT often asks us to post the Case number in the forum thread, which allows them to find that bug-report if they look at your post.

Following these steps will increase the chance that UT is looking at the issue tremendously.

Last but not the least, you can disable windows defender on your system and can try running application by admin rights. This sometimes solve the issue too because the antivirus or any firewall may block this DLL too. These issues happen mostly on network or in old machines, whose application requirements are either not met or they are too slow to perform their actions. Therefore, you can disable firewall or take out network cable if you are accessing the application online.

If issue persists, it is highly recommended to take system to some expert who can see and tell you exact solution for the same because the ones we have given are the general solutions and they may vary as per environment as well as equipments used
