Chrome won't open iTunes desktop links
As of Chrome 58 on macOS, this setting is in a file called Preferences in the relevant profile folder for your Chrome application files. In other words, something along the lines of:


~/Library/Application Support/Google/Chrome/Default/Preferences
~/Library/Application Support/Google/Chrome/Profile1/Preferences
~/Library/Application Support/Google/Chrome/Profile2/Preferences


depending on whether or not you have multiple user profiles and which one you are using.

Inside that file, search for itmss and change the entry to false so that Chrome opens iTunes links, in other words:

"itmss":false,

The equivalent entry for the Mac AppStore is macappstores, i.e.:

"macappstores":false,

Before making this change, be sure to:


quit Chrome
make a copy of the original file in case things get messed up
