Installing Mastin Labs Presets in Windows 10

I've recently discovered the joys of Mastin Lab's film presets for Adobe Lightroom and Photoshop.  These presets give my photos a look similar to what I had when I used to shoot film.  They're easy to use, and give great results.   The photo at left is from a couple of years ago, and re-edited in Lightroom using the Portra 400 preset.
Unfortunately, the installation instructions leave something to be desired.  The Lightroom instructions for Windows only cover Windows Vista, XP, and Windows 7 (Does anyone even USE Vista anymore?), and are lacking in some key specifics.  The Adobe Camera Raw (Photoshop) instructions don't cover Windows at ALL, only the Mac.  I've used computers as long as I've had a camera (43 years), and it still took some trial and error for me to complete the install.  So as a public service to my fellow photographers, here are some step-by-step instructions.  I have the Portra presets, so you will see that in the examples.  I'm using Windows 10, and the Creative Cloud versions of Photoshop and Lightroom, so your results may vary if you have something different.

Installing the Presets in Lightroom

1. Once you have downloaded the presets, you should see the download listed at the bottom of your browser window.  This is a compressed file.  Double click on it to open a window showing what is in the compressed file.
2. At the top of the window will be a button labeled "Extract All".  Click on that button, select where you want to put the decompressed files, and you will get another window showing the decompressed files.
3. Double click on the "Mastin Labs Portra" folder, and then double click on the "LR" folder.
4. You should see three folders listed, one each for Nikon, Canon, and Fuji.  I only shoot Nikon, so I selected (single click) the Nikon folder, and then right-clicked and selected "Copy".
5. Start Lightroom.  Select "Edit" -> "Preferences".  In the popup window click on the "Presets" tab, and then click on the button labeled "Show Lightroom Presets Folder..."
6. Double click on the "Lightroom" folder, and then double click on the "Develop Presets" folder.
7. You should see a list of your develop presets.  Right-click in this window and select "Paste".  The Nikon folder we copied in Step 4 should appear on the list.
8. Close the "Develop Presets" file window you are in.  The Lightroom "Preferences" popup window should still be open.  Click on the button in the lower left corner marked "Restart Lightroom".

That should do it!  When you go to Lightroom's Develop module you will see your Mastin Labs presets listed in the "Presets" window on the left side of the screen.

Installing the Presets in Adobe Camera RAW (Photoshop)

Note:  These first two steps are the same as for the Lightroom install.  If you have already installed the presets for Lightroom, you can skip to step 3.

1. Once you have downloaded the presets, you should see the download listed at the bottom of your browser window.  This is a compressed file.  Double click on it to open a window showing what is in the compressed file.
2. At the top of the window will be a button labeled "Extract All".  Click on that button, select where you want to put the decompressed files, and you will get another window showing the decompressed files.
3. Double click on the "Mastin Labs Portra" folder, then double click on the "ACR" folder, and finally double-click on the Nikon folder.
4. You should see the Nikon presets listed.  Click on the "Select All" button at the top of the window, and then click on the "Copy" button.
5. On the left side of the file browser window, click on your "C:" drive.  Then double click on the"Users" folder, and double click on the folder with your user name.
6. Double click on the "AppData" folder.  This is a hidden folder, so you might have to make it visible first.  Then double click on the "Roaming" folder, then on the "Adobe" folder, then the "CameraRaw" folder and finally the "Settings" folder.
7. There probably won't be much in the "Settings" folder, just an "Index.dat" file.  Click on the "Paste" button at the top of the window.  Your presets should now be listed.
8. Close the "Settings" file window you are in.

That should take care of it.  When you go in to Photoshop and try to open a RAW file, ACR will start up and your presets will be available.
