Description

After installing ImageMagick from the official Windows 64bit installer, all operations will basically fail to complete due to the error magick: no decode delegate for this image format `[format name]' @ error/constitute.c/ReadImage/746.

Trying to open the built in image "rose" will not work. The output of magick rose: rose.jpg is as follows:
magick: unable to open image 'rose:': Invalid argument @ error/blob.c/OpenBlob/3571.
magick: no decode delegate for this image format `' @ error/constitute.c/ReadImage/746.

magick -version shows Delegates (built-in): bzlib cairo flif freetype gslib heic jng jp2 jpeg jxl lcms lqr lzma openexr pangocairo png ps raqm raw rsvg tiff webp xml zip zlib, however, they don't seem to actually work in practice.

magick identify -list format simply returns nothing.

I've made sure to have the Visual C++ Redistributables installed, and re-installed ImageMagick itself many times.
I've read through #6783 but as that seems to be caused by other software the user recently updated (which I don't use) I decided to make this issue anyway, apologies if it actually is a duplicate. Please let me know if I can provide some more information to diagnose the issue!

Steps to Reproduce

1. Install ImageMagick 7.1.1-28 from the official installer on Windows 11
2. Run magick rose: rose.jpg
3. Note the error produced.

What do get returned from

magick -version

Show everything.

Did you install IM 7 or the legacy IM 6 from the installer?

Which version from https://imagemagick.org/script/download.php#windows did you install? Is it compatible (64-bit versus 32-bit) to your computer?

I can't reproduce the problem on Windows 11.

I installed from the given link, https://imagemagick.org/archive/binaries/ImageMagick-7.1.1-28-Q16-HDRI-x64-dll.exe . It works fine for me, reading rose:, and writing and reading PNG and JPG files. magick -version says:

I have IM 7. I installed the version I stated in the my original post in the version section, 7.1.1-28 Q16-HDRI x64, it's the most prominent link on the page under the Windows section. I have a 64 bit system.

For anyone else having this problem, I ended up clumsily "fixing" it by downloading the portable release for the same version, and copying all the files from the portable release into the existing install folder, without replacing. The portable release worked fine by itself as well.
