What are pfm.dat Error Messages?

Dynamic Link Library pfm.dat Errors

pfm.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like pfm.dat, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Corel VideoStudio Pro) could share the same pfm.dat file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DAT file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when pfm.dat is attempted to be loaded either when Corel VideoStudio Pro is starting up, or in some cases already running. Some of the most common pfm.dat errors include:

• Access Violation at address - pfm.dat.
• pfm.dat could not be found.
• Cannot find C:\Users\Tester\AppData\Roaming\Ulead Systems\Corel VideoStudio Pro (x64)\22.0\pfm.dat.
• Cannot register pfm.dat.
• Cannot start Corel VideoStudio Pro. A required component is missing: pfm.dat. Please install Corel VideoStudio Pro again.
• Failed to load pfm.dat.
• The application has failed to start because pfm.dat was not found.
• The file pfm.dat is missing or corrupt.
• This application failed to start because pfm.dat was not found. Re-installing the application may fix this problem.

Your pfm.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Corel VideoStudio Pro), or deleted by a malware infection. Furthermore, pfm.dat file corruption could be caused from a power outage when loading Corel VideoStudio Pro, system crash while loading pfm.dat, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
