Loadlibrary Failed With Error 126: How to Fix It in 5 Steps
Relaunch the problematic program to see if this fixes the issue
- The Loadlibrary function, used to load dynamic libraries, can sometimes fail if there's a conflict in your graphic cards.
- Missing DLL files may also play a part, but first, restarting the problematic application before any advanced troubleshooting is important.
When you try to run an application program, it checks if there is a particular DLL file in its directory. If the DLL is not found, it will search for another DLL file in its directory and load it into memory. It will then return an error code like 126 if it is not found.
While you can get away with ignoring some errors, you must watch out for this one. If it has occurred, your application will not run properly, and you might get serious problems like poor performance or even a PC crash due to this error message.
What is LoadLibrary failed with error code 126?
LoadLibrary failed with error code 126 is a generic error message displayed when an application fails to load one of its DLL files. If the application has tried to use a DLL and it cannot be found, or if the specified module could not be created, then this error will occur.
Other reasons include:
- Bad or corrupt DLL file – If you have recently upgraded your computer or installed a new piece of software, this may be the problem.
- Security settings – You may have some security settings on your system preventing your application from accessing the files from the library file. For example, if you have disabled user access to directories or limited administrative privileges.
- The file doesn’t exist – If your application requires a specific DLL, make sure it is available on your system. It is possible that the file you’re trying to load doesn’t exist on your computer.
- Conflicting graphic cards – If you have more than one GPU installed, Windows will try to use whichever one has the best performance at any given time. Sometimes, Windows can’t detect the second GPU.
- Wrong registry setting – You may also have made the wrong registry setting for your operating system. It can be a bad path or location or an incorrect value or type of setting.
