Key notes

Owned by JetBrains, dotPeek is a popular decompiling software that integrates into Visual Studio and facilitates the decompilation of all sorts of assembly files, including Dynamic Libraries or DLLs.

However, several of our readers have reported that they cannot access and decompile a .dll file using dotPeek as the DLL is not supported.

Why do I get the DLL not supported error in dotPeek?

If a DLL is flagged as not supported in the assembly list of dotPeek, it may be because of the following reasons:

If you are also struggling with the same issue, here are the proven ways of resolving the problem.

How do I fix the not supported error in dotPeek?

Before you jump to the complex solutions listed below, perform the following actions:

If the problem still exists, employ the following fixes.

1. Use a dedicated DLL fixer

There are several reasons you encounter such an error in dotPeek, and troubleshooting such system-level issues is hard to tackle. Hence, you are recommended to employ a dedicatedDLL fixer toolthat is capable of fixing DLL-related errors without requiring your intervention.

2. Repair the system files

The SFC and DISM tools will scan all the protected system files on your computer and replace the corrupt or modified system images with the cached version stored in a compressed folder.

After the repair is successful, you will no longer encounter the DLL not supported error in dotPeek, and you can decompile it successfully.

3. Disable real-time protection

Windows Defender and third-party antivirus often consider certain DLL files as a potential threat and restrict and block them on your computer. To prevent Windows Defender from doing so, you can disable the real-time protection feature of Windows Security before you launch the dotPeek application.

If you rely on third-party antivirus to stay protected, you cancreate an exceptionfor the affected DLL file to let it bypass the restrictions.

4. Manually download a DLL

While we do not favor downloading software, apps, and DLLs from random online sources, if the error persists, you can manually download and replace the DLL file not supported in dotPeek with a legitimate version.

However, it is extremely necessary to proceed with caution and only download the files from trusted websites likedll_files.com, which house genuine DLLs and not malicious software masquerading as them.

After the download is successful, extract the DLL file from the ZIP or RAR archive, and then replace the DLL not supported by dotPeek with this version.

After performing these steps, restart your PC and re-launch the dotPeek app. You will no longer encounter the un-supported error when opening DLL files with dotPeek.

Those are the fixes that will prove effective when you are unable to decompile a DLL file as it is not supported in dotPeek.
