Key notes

Recently, users faced trouble withamfrt64.dlloramfrt32.dll(the DLL version for 32-bit architecture).

For some, the DLL didn’t open, leading to issues with installed programs, primarily video editing, while others found thatamfrt64.dllwas not digitally signed.

What is the amfrt64.dll file?

The DLL is installed by the AMD drivers and is linked to theAdvanced Media Framework (AMF). The latter helps ensure the seamless encoding and decoding of videos, amongst other similar tasks. If you don’t have AMD graphics, the DLL shouldn’t be ideally installed.

What can I do if amfrt64.dll failed to open?

Before we start with the slightly complex solutions, try these quick ones:

1. Use a dedicated DLL repair tool

For DLL errors, whether the file is corrupt or not loading, use aneffective DLL repair tool. They will look for any problematic or missing files on the PC, and then download a fresh copy from their extensive library hosting thousands of DLLs.

The process negates the need to download DLL files from the web, which is considered risky, given that these can infect the PC with malware.

2. Reinstall the AMD graphics driver

If reinstalling the AMD driver doesn’t help with theamfrt64.dll failed to openerror, use areliable driver uninstaller toolto remove all related files and then perform a clean install.

3. Update the AMD graphics driver

When it’s a bug in the installed version to blame foramfrt64.dll,update the graphics driver. And if Windows can’t find one, go to the manufacturer’s website, locate the latest version, andmanually install the driver.

This also helps whenNvapi64.dll is throwing errors.

4. Reinstall the affected application

We often getamfrt64.dllerrors with OBS. If reinstalling it doesn’t work, the problem might arise due to thepoor performance of the PC. In this case, try lowering the resolution and also go with 30 FPS (Frames Per Second).

ForFFmpeg, setting the correct codec version did the trick. This worked for a few users (replace the version):ffmpeg4.4 -i input.mp4 -codec:v h264_qsv output.mp4

5. Perform a system restore

If you havecreated a restore point earlieror Windows is configured to do so automatically, performing a system restore will revert any recent changes that trigger theamfrt64.dllerror.

Why is amfrt64.dll not signed?

Theamfrt64.dllfile is not signed, but that doesn’t necessarily indicate the file is unsafe or corrupt. For some, even thenvcpl.dllfile, linked to NVIDIA graphics, is not signed.

If you believe that it’s a malware disguised as the DLL, scan the file using the built-in Windows Security or aneffective antivirus tool.

That’s all you need to know about theamfrt64.dlland all related errors. As long as the installed programs and associated functionalities work fine, you shouldn’t be too worried about the DLL not being signed!
