    Eventually I ended up on a blogpost, which is a repost of a deleted post by PhilipD which was posted in a wrong format and not corrected. So the question was deleted.

    I'm reposting the answer of PhilipD here so it can be found more easily for people encountering the same problem, because it took me half a day of frustration to find the blog post that worked. These steps detail a 32 bit installation. I did a 64 bit installation, for my 64bit php.


    This is on a Windows Server 2012R2 (64-bit) server, using IIS as the web server application. However, I installed the 32-bit version of all the ImageMagick-related software because the web server application (IIS) is 32-bit. The following shows versions that were current/latest as of October-2017.

    1. Download the ImageMagick installer

    • Go to http://www.imagemagick.org/

    • Click "Download" from the menu bar

    • Then "Windows Binary Releases" in the top links or scroll down
    • Select the "Win32 dynamic at 16 bits-per-pixel component", make sure you select a dynamic component and not a static.

    2. Download the php module for ImageMagick

    • Go to http://windows.php.net/downloads/pecl/releases/imagick/
    • Select the highest version that's not an "RC" (Release Candidate) version – currently 3.4.3
    • Select the entry for the version of PHP (7.1), for VC14, x86, and "NTS" (Non Thread Safe) for IIS
    • Download and save the ZIP file.

    3. Download the dependencies package for PHP to load/use ImageMagick

    • Go to http://windows.php.net/downloads/pecl/deps/
    • Select the "ImageMagick" package with the highest version number
      • *note that this might not be the same version as the item in (1.) above
    • Select the "vc14" and "x86" version*

    4. Unblock each of the downloaded files

    This may or may not be necessary depending on how you downloaded it, but you should always check and "unblock" downloaded files if needed.

    • Right-click on each file and select “Properties” from the popup menu
    • if the properties dialog shows the text “This file came from another computer and might be blocked to help protect this computer”,
      • click the “Unblock” button
      • click OK.

    If you don’t “unblock” the downloaded files, especially for ZIP files, the individual files that are installed or copied can still be marked as “blocked” and this can sometimes cause some strange issues when running the software.

    5. Installing the Imagick Application

    • Run ImageMagick-7.0.7-8-Q16-x86-dll.exe to install it
    • Accept the license agreement
    • Accept the defaults on each screen in the install process.

    After the installation completes, to test that it was successful, open a command prompt and run the following two commands:

    magick wizard: wizard.jpg
    magick wizard.jpg win:
    

    This should display an "IMDisplay" window showing a sketch/image of a wizard at an easel creating a Mona Lisa portrait.

    6. Install the dependencies

    • Unzip the file you downloaded in step 3.
    • Go into the bin directory
    • copy the IM_MOD_RL_*.dll files (125 files) into the folder for the installed version of ImageMagick, such as C:\Program Files (x86)\ImageMagick-7.0.7-Q16
    • Go back into the bin directory
    • copy the CORE_RL_*.dll files (20 files) into the folder for the installed version of ImageMagick, such as C:\Program Files (x86)\ImageMagick-7.0.7-Q16 * * On the prompt if you wish to overwrite/rename, select overwrite
      • Note, this will break the command version of Imagick. magick: Wrong JPEG library version: library is 80, caller expects 62

    7. Installing the Imagick php extension dll

    • Unzip the file downloaded in step 2.
    • copy the file php_imagick.dll to the "ext" folder for the installed version of PHP on the server, such as C:\php\7.1\ext.

    Do not copy the CORE_RL_* files
    In some articles on the web, you will see instructions to also copy the CORE_RL_* files from this kit to replace the files in the ImageMagick folder, but this is incorrect; the appropriate versions of these files were copied in the step 6.

    8. Modify PHP.ini

    • Edit the php.ini file in the PHP software folder, such as “C:\PHP\7.1\php.ini”
    • Add the following line to the section containing the other extensions:

         extension=php_imagick.dll
      

    9. Reboot the server.

    Restarting IIS does not seem to be sufficient, you need to reboot the entire machine. This probaly has to do with that IIS doesn't recognize the PATH entry Imagick has entered.

    10. Test PHPINFO

    • Create a PHP file in the web root, containing the following:

    • Access this file in a web browser,

    • Search for the “Imagick” section that should now exist in the PHPINFO output.

    It should look like the following:

    imagick imagick module: enabled imagick module version 3.4.3
    imagick classes Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator, ImagickKernel
    Imagick compiled with ImageMagick version ImageMagick 6.9.3-7 Q16 x86 2016-03-27 http://www.imagemagick.org

    ImageMagick copyright Copyright (C) 1999-2015 ImageMagick Studio LLC
    ImageMagick release date 2016-03-27
    ImageMagick number of supported formats: 216
    ImageMagick supported formats 3FR, AAI, AI, ART, ARW, AVI, AVS, BGR, BGRA, BGRO, BIE, BMP, BMP2, BMP3, BRF, CAL, CALS, CANVAS, CAPTION, CIN, CIP, CLIP, CLIPBOARD, CMYK, CMYKA, CR2, CRW, CUR, CUT, DATA, DCM, DCR, DCX, DDS, DFONT, DJVU, DNG, DOT, DPS, DPX, DXT1, DXT5, EMF, EPDF, EPI, EPS, EPS2, EPS3, EPSF, EPSI, EPT, EPT2, EPT3, ERF, EXR, FAX, FITS, FPX, FRACTAL, FTS, G3, GIF, GIF87, GRADIENT, GRAY, GROUP4, GV, H, HALD, HDR, HISTOGRAM, HRZ, HTM, HTML, ICB, ICO, ICON, IIQ, INFO, INLINE, IPL, ISOBRL, ISOBRL6, J2C, J2K, JBG, JBIG, JNX, JP2, JPC, JPM, JPT, JSON, K25, KDC, LABEL, M2V, M4V, MAC, MAGICK, MAP, MASK, MAT, MATTE, MEF, MIFF, MKV, MONO, MOV, MP4, MPC, MPEG, MPG, MRW, MSL, MTV, MVG, NEF, NRW, NULL, ORF, OTB, OTF, PAL, PALM, PAM, PATTERN, PBM, PCD, PCDS, PCL, PCT, PCX, PDB, PDF, PDFA, PEF, PES, PFA, PFB, PFM, PGM, PICON, PICT, PIX, PLASMA, PNM, PPM, PREVIEW, PS, PS2, PS3, PSB, PSD, PTIF, PWP, RADIAL-GRADIENT, RAF, RAS, RAW, RGB, RGBA, RGBO, RGF, RLA, RLE, RMF, RW2, SCR, SCREENSHOT, SCT, SFW, SGI, SHTML, SIX, SIXEL, SPARSE-COLOR, SR2, SRF, STEGANO, SUN, TEXT, TGA, THUMBNAIL, TIFF, TIFF64, TILE, TIM, TTC, TTF, TXT, UBRL, UBRL6, UIL, UYVY, VDA, VICAR, VID, VIFF, VIPS, VST, WBMP, WEBP, WMF, WMV, WPG, X3F, XBM, XC, XCF, XPM, XPS, XV, YCbCr, YCbCrA, YUV

    Important:
    If the “supported formats” section does not show any formats, or only shows a small number of formats, then the most likely cause is that you missed copying one or more of the IM_MOD_RL_* or CORE_RL_* DLL files into the ImageMagick folder, or you copied them from the “php_magick” kit instead.

    11. Test image generation using ImageMagick in PHP

    Create a PHP file in the web root, containing the following (I copied this from one of the entries in this item Verify ImageMagick installation ):

    <?php
    error_reporting(E_ALL); 
    ini_set( 'display_errors','1');
    /* Create a new imagick object */
    $im = new Imagick();
    /* Create new image. This will be used as fill pattern */
    $im->newPseudoImage(50, 50, "gradient:red-black");
    /* Create imagickdraw object */
    $draw = new ImagickDraw();
    /* Start a new pattern called "gradient" */
    $draw->pushPattern('gradient', 0, 0, 50, 50);
    /* Composite the gradient on the pattern */
    $draw->composite(Imagick::COMPOSITE_OVER, 0, 0, 50, 50, $im);
    /* Close the pattern */
    $draw->popPattern();
    /* Use the pattern called "gradient" as the fill */
    $draw->setFillPatternURL('#gradient');
    /* Set font size to 52 */
    $draw->setFontSize(52);
    /* Annotate some text */
    $draw->annotation(20, 50, "Hello World!");
    /* Create a new canvas object and a white image */
    $canvas = new Imagick();
    $canvas->newImage(350, 70, "white");
    /* Draw the ImagickDraw on to the canvas */
    $canvas->drawImage($draw);
    /* 1px black border around the image */
    $canvas->borderImage('black', 1, 1);
    /* Set the format to PNG */
    $canvas->setImageFormat('png');
    /* Output the image */
    header("Content-Type: image/png");
    echo $canvas;
    ?>
    

    Run this PHP file in a browser. It should display an image containing the text "Hello World!".

    Hello world with freehand circle and arrows pointing to it

    12. Check for errors

    Check the php-errors.log file for any errors.
    You can find the defined location of the php-errors.log file in the php.ini file. Check this file for any recent errors related to the ImageMagick installation.

    PDF Files require Ghostscript
    After installing and setting up all of the above, ImageMagick could be used in PHP to convert images, but it could not be used to convert PDF files to images. For this final step, it seemed to be necessary to also install Ghostscript - from https://www.ghostscript.com/download/gsdnld.html and it only worked correctly if I installed the 64-bit version of Ghostscript (even though everything else that I installed was the 32-bit version). Installing Ghostscript was all that was needed; no changes to php.ini or any other configuration was required.
