Cygwin X error failed to activate core devices

Asked By 100 points N/A Posted on -

Hi experts,

I get this weird error message when I try to install Cygwin in the system. For your information, I have windows 8 operating system 64-bit and 500 GB hard disk. Is the dll is corrupted or missing? Please help me find the root cause of this error. Your help is great. Thanks.

Such issue is related to “cygwin1.dll”. This file is usually located on “C:cygwinbin” folder. Check if your system contains many “cygwin1.dll” files. If found, delete all except the original one.

Also, uninstall Cygwin and then install the latest version. That will install all the latest files and components on system. Download Cygwin.

Also, you can add the DLL file inside your system manually. Download cygwin1.dll. Paste it inside “C:WindowsSystem32”, open Command Prompt with administration privilege, run “regsvr32 cygwin1.dll” command. This will register the DLL file and make it available to all programs.

Now, your problem should have solved.
