--------------------------+-----------------------------
 I’ve done some research:

 1. Windows 10, Chrome 57.0.2987.110 (64-bit);
 2. in my opinion it’s not related to server’s setup: on other browsers –
 it works;

 3. previous instances of WP 4.7.3 – Select Files works;
 4. new instances of WP 4.7.3 – Select Files no reaction;

 5. it’s partialy Plupload/Moxie issue
 (http://www.plupload.com/punbb/viewtopic.php?id=14914) – it’s used on that
 Select Files button by WP core, to generate hidden file input with accept
 argument which holds accepted mime/file types;

 6. workaround # 1:
 6.1. open (using chrome, win10) wp-admin > media > library > click “add
 new” (while in grid, not list) – “Drop files anywhere to upload” block
 appears with Select Files button;
 6.2. open chrome developer console, find that hidden file input, it’s
 right before </body> tag, named with eg.
 id=”html5_1bblpaq4r1ee0e6ich21tge1mus5″ and it has big accept argument
 with file types;
 6.3. copy “accept” attribute big value to your favourite text editor, find
 “application/zip”, change it to “application/x-zip”, then copy-replace new
 big list of mimes/file-types to that “accept” attribute (don’t refersh
 page);
 6.4. click on Select Files – it should work;

 7. workaround # 2:
 7.1. open chrome settings, show advanced settings at the bottom, under
 Privacy uncheck “Protect you and your device from dangerous websites”;
 7.2. refresh media library page and go to Select Files (like in 6.1.
 explanation) – the button should work.

 8. I’ve tried application/x-zip-compressed – bug not resolved – button
 didn’t work.
 9. I think it’s more chrome bug, related to recently strenghtened
 malware/virus protection.
 10. wp core team should make an exception for this situation to use
 application/x-zip instead of application/zip with Plupload/Moxie. or just
 to work with chrome team to sort out this.
