Starting the ImageMagick process on a Windows server with the error "specified module not found."

I use ImageMagick to convert PDF files to PNG. Starting a process from my web API project works locally as long as I start Visual Studio as an administrator. When you move the solution to the server, the ImageMagick process fails with the following error

convert.exe: cannot load module `C: \ Program Files \ ImageMagick-6.9.0-Q16 \ modules \ coders \ IM_MOD_RL_PNG_.dll ': the specified module was not found.

I have both ghostscript and ImageMagick, as they should be on the server. What could be the reason for this? I can check if the module really exists on the server.

The solution to this problem in my situation was to set the environment variable for ImageMagick directly in the code where I called the process.

System.Environment.SetEnvironmentVariable("Path", @"C:\Program Files\ImageMagick-6.9.0-Q16");

Obviously, even if the environment variable is set on the server, it may not find it due to the difference in runtime.

In my case, after a new installation of Imagemagick, I got a simillar error (I can’t load the module). What helped was simple:

Reboot system

Probably because the PATH system variable or something like this should take effect.

In my case, I was able to solve this problem using a portable version, so she does not need to find anything, since all this is built into exe.

If you just installed ImageMagick and are trying to start it from the command line, you will need to open a new command prompt window with the updated% PATH% environment variable.

You can try something with SETX, but opening a new command prompt window seems a lot easier.

Restart Visual Studio or any IDE (even your prompts, close and reopen them).

The system path is not updated, it causes this error in my situation.

Can imagemagick find libpng? Is it really installed? Are you calling ImageMagick convert.exe or Windows convert.exe?

 convert.exe -version

should show png in the delegate list? What do you find from this team?
