Mediawiki on Microsoft Windows 2008 R2. Thumbnail problem

[halker]

Hello,
I installed MediaWiki 1.28.0-0 and ImageMagick-7.0.4-0-Q16-x64 on Microsoft Windows 2008 R2
When I try to add some graphic files, i get this error:

Error creatintg thumbnail. Invalid Parameter - "80"

Error code: 4

What does it mean?

We don't maintain the MediaWiki project so we cannot help you with this. You should ask for help at https://www.mediawiki.org/ instead.

Just guessing, but MediaWiki may require ImageMagick version 6. You installed version 7.

I cannot find binary version of ImageMagick 6. Is it possible to download it from somewhere? I would like to avoid this whole crazy compiling thing

EDIT:
Nevermind. I found it.

Now i have this error

unable to load module `C:\ImageMagick\modules\coders\IM_MOD_RL_JPEG_.dll': The specified module could not be found.
