ShellExt issue with libJPEGXL 1.11.5 for windows 11

Post by simon »

Hello,
An issue already noticed in the ShellExt repository: windows explorer crashes when ShellExt is used on a jpegXL file. This seems to be due to a change in libJPEGXL.dll in the MP1.11.5 zip package (replacing it by libPEGXL.dll from the MP1.11.2 zip package solves the issue)

BTW, note that all links to download ZIP packages of all versions (for windows at least) points to the latest version (1.11.5), so it makes hard to download a previous version for testing (fortunately I had a copy of MP1.11.2 zip on a USB key)

cheers

Thank you both. This was the only thing that actually fixed the issue for me, which persisted even in 1.11.6

On my side, no more crashes with the latest version, but no thumbnail shown when using shellEx on a jpeg-xl file (contrarily to what happens with jpeg, tiff or png files)
