The minor point versions are all compatible, so just change the number to 1.8.6 like the instructions say and everything will work.
In fact the theme switcher works.
But the themes with the theme roller made in version 1.87 put a bug in the code.
If I create new account and click on date of birth.
The calendar does not open.
At the bottom of the browser gets an error. Clicking it opens a window where I states:

If I return to the original theme oscommerce this does not happen.
If it was something with the installation of the oscommerce theme switcher in the original theme would not work.
So I think it is an incompatibility between version 1.8.7 and the theme switcher.
