Ctor.dll Error: Application Failed to Start

Ctor.dll Error: Application Failed to Start

Hi Zachary,

Causes of Ctor.dll Errors:

The issue may occur due to the removal or corruption of the ctor.dll file.

In some cases, ctor.dll errors due to a registry problem, a virus or malware issue or even a hardware failure.

Fixing of Ctor.dll Errors: 

1. Please start Computer in Safe Mode to complete the following steps if you are unable to access Windows normally due to the ctor.dll error.
2. Restore ctor.dll from the Recycle Bin if you it is present. The easiest possible cause of a "missing" ctor.dll file error is that you've mistakenly deleted it. If it is not present in Recycle Bin, you may be able to recover ctor.dll with a free file recovery program.

Note:If you are confident you have deleted the file yourself and it was working properly before you did that then recover a deleted copy of ctor.dll with a file recovery program.

• Run a Full virus/malware scan of your system.
• You can do System Restore to the check point when the application was working properly.
• Try to reinstall the program that uses the ctor.dll file. If the ctor.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.
• Roll back a driver to a previously installed version if ctor.dll errors began after updating a particular hardware device's driver.
• Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the ctor.dll file. If this DLL file is related to Microsoft, the System File Checker tool will restore it.

I hope these will resolve the issue.
