off the top of my head... at work, no internet at home
I went to
http://gmic.eu/files/prerelease/ and downloaded an installable version for windows 64
it may have been this one.
gmic_gimp_gtk_win64.exe 10-Mar-2017 15:18 7.2M
took it home on a flashdrive
and ran the install.
Gmic 2.0.0 now ran (and still have 1.7.9) - but was missing many filters,
since I don't have internet at home where I use Gimp it couldn't update
I went back and downloaded the update from type
gmic.eu/update200.gmic in the browser search box.
The 10 files were .dll s and if you downloaded the same as I did, they
were all dated 03 10 17 -- I have been running older versions with
no error messages, though I moved the older dll's into a backup folder just in case.
and moved the update200.gmic to
c:usersMYUSERNAME%appdata%gmicupdate200.gmic
so both versions are working.
I run older versions, but I must remove the .exe file from
plugins (usually just rename it with the version number on it and remove .exe) and
put the version I want .exe into plugins (usually just remove the version number and
add .exe to the end).
I leave all the update173 update174 etc update200 files in the %appdata%gmic folder and it doesn't bother anything (I think each version looks for its own updateXXX file).
