    File Association for iTunes Store (.itmss)

    I use Amtrak Guest Rewards a lot. They have an online shopping mall and one of the ways to earn rewards is to buy items on iTunes. It used to be that when I clicked on the link to open iTunes via the AGR "shopping mall" page, it would open iTunes and go right to the iTunes store. Today, I tried it and I get a window that pops up with "This link needs to be opened with an application." And the only thing it lists is "iTunes.AssocProtocol.itmss". If I click on that, I get "This file does not have an app associated with it for performing this action."

    So I went into settings (Windows 10 Pro version 1803) and found the place where I can choose the app for just about every file link. I see an option for .itms (which has iTunes set as the default), but there is NOT a listing for .itmss files. Why would this change if I haven't changed anything on my system and I just used this option a few months ago without any problem? How do I get this to open correctly?

    No - it is .itmss. Note, I tried adding iTunes.exe myself, which is why it is also now listed. I would show you a picture of the window, but it seems I can only save it as a .bmp file, which this forum does not allow.

    Did you first notice this after upgrading to 1803? If so, try reinstalling itunes.

    You can use any number of free screen capture tools which save in different formats.

    Or (quite crude but good enough) - open file in Paint, save it, choosing the format you want.

    BMP is large and uncompressed so is inefficient.

    If you need to create a new file type, you could use this:

    You could also try repairing or reinstalling itunes of course.

    However, itmss seems to be a protocol:
