FX File Complications


Troubles Opening FX Files

Microsoft Visual Studio is Not Installed

If you attempt to load your FX file, you experience a message such as "Can't Open FX Files". Usually, this is because you do not have Microsoft Visual Studio for %%os%% installed. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: If you have another software that you know opens FX files, you can select it by hitting the "Show Apps" button.


Outdated Microsoft Visual Studio

In other instances, your Direct3D Effects File file version may not be supported by your version of Microsoft Visual Studio. If you've got the wrong version of Microsoft Visual Studio installed, you'll need to install the correct version. This issue mainly occurs when your Direct3D Effects File file was created by a newer version of Microsoft Visual Studio than you have on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the FX file, selecting "Properties", and looking at the version information.


Summary: Not having the right Microsoft Visual Studio version on your computer can cause problems opening FX files.


Associated Difficulties Loading FX Files

In the majority of cases, installing the right version of Microsoft Visual Studio will resolve your issue. There can be external issues inside of %%os%% that are causing these errors when opening FXs. These issues include:

  • FX file type Registry entries are wrong
  • The FX file description within the Windows Registry was removed
  • Partial installation of Microsoft Visual Studio that did not fully complete
  • The FX itself is corrupted
  • Your FX is infected with malware
  • Device drivers of the hardware associated with your FX file are corrupt or out-of-date
  • Your PC doesn’t have enough available resources to open the Direct3D Effects File file
