fltlib.dll is a file used in the Windows 7 system to help your computer run the “Filter Library” on your system. The fltlib.dll file is kept inside the “C:\Windows\System32” folder of your PC and is used regularly by a variety of Windows systems. The job of the file is to act as a library for the various filter operations that Windows can perform. This means that if a program such as “Excel” wants to filter data on your PC, the fltlib.dll file will be called to help process the commands. Although this file has been an integral part of the Windows system for many years, it’s known for causing a lot of errors on your computer, which can be fixed by using the tutorial on this page.
What Is The FltLib.dll Error & What Causes It?
Fltlib.dll errors will generally show in this format:
- “fltlib.dll Not Found”
- “This application failed to start because fltlib.dll was not found. Re-installing the application may fix this problem.”
- “Cannot find fltlib.dll”
- “The file fltlib.dll is missing.“
There are a number of reasons why this error may show, from having a corrupt / damaged registry to your PC trying to run out-of-date software. If you want to resolve the errors you’re seeing, you should first look at the actual file, and then any possible issues that Windows may have with it.
How To Fix FltLib.dll Errors
Step 1 – Update Windows
Since fltlib.dll is a crucial Windows file, the best way to begin to fix the error is to update your system. This can be done in two ways, which are detailed below:
You can update online
- Click onto the Microsoft Update Website
- Download any of the updates you require
- Install the updates
- Restart your PC
You can update with “Windows Update”
- Click Start > All Programs > Windows Update
- Download all the updates your computer needs
- Install the updates
- Restart your PC
This will provide Windows with all the files, settings and options which your computer will use to help it run. Microsoft are continually releasing new versions of Windows to help improve various problems, as well as fix a variety of errors on your PC. Since fltlib.dll is not put onto your system through a third party program, it’s best to fix any of the errors it has by updating your system through the Windows Update procedure.
Step 2 – Manually Replace fltlib.dll On Your PC
If you still get the error after reinstalling the software on your system, it suggests you have a problem with the fltlib.dll file itself. You may wish to then try this procedure to replace the file & correct the issue on your PC:
2) Unzip the fltlib.dll file onto your computer’s hard drive
3) Locate the current fltlib.dll on your system
(will likely be in C:\Windows\System32)
4) Rename the current fltlib.dll to fltlibBACKUP.dll
5) Copy & paste the new fltlib.dll into C:\Windows\System32
6) Click Start > Run (Or search”run” on Vista & Win7)
7 ) Type “cmd” in the box that appears
8 ) Type “regsvr32 -u fltlib.dll” on the black screen & Press Enter
9) Type “regsvr32 fltlib.dll” on the black screen
10) Press enter
This will basically replace the steam.dll file on your system, which should correct any issues the file may have developed on your PC. This generally works to fix most cases of DLL errors, but may not work for you.
Step 3 – Clean Out The “Registry”
One of the main causes of fltlib.dll errors is actually Windows itself… and more specifically, a central part of Windows called the “registry”. This is a database which stores all the settings and options which Windows uses to run, and is the place where the likes of your desktop wallpaper, latest emails and login details are stored. Although the registry is easily one of the most important parts of the Windows system, it’s also the main cause of a lot of DLL errors on your PC. The problem is that the registry contains a large list of DLL files which all your software uses to run (that’s why you need to “register” a dll on your computer in order for it to be usable). The list of DLL files on your PC may be extremely important, but is continually getting damaged – leading your computer to run much slower and with a lot of errors as a result. In order to fix this problem, it’s recommended you use a “registry cleaner” tool to scan through your system and fix any potential registry errors which are leading the steam.dll error to show. This should stop the fltlib.dll error on your PC and prevent any further errors from occurring.
