The 'give-us-your-email-address' put me off, but not needed 
The zip to download is this one:
That contains the two profiles ISOcoated_v2_300_eci.icc and ISOcoated_v2_eci.icc - that one the same as I used. Each about 1.83 MB
In linux, the place to put them is your home folder ~/.local/share/color/icc but for Windows I understand it uses Control panel > Color management > All Profiles > Add
For me, that puts the additional profiles top of the list. Maybe down the list in Windows. (for Gimp you can put then anywhere, and use Select color profile from disk option)
Then in Inkscape it should look like this
That little svg attached. Does it work in your Inkscape ?
