As an alternative to Wallace's file.
You can still get old versions on the internet archive site. For example:

EDIT: OOPS - Not QT but GTK
Lots of the listed files are not available - you get a not archived message but that bottom one downloads
https://web.archive.org/web/20160408003 ... _win64.zipThat unzips to a folder with all the dependencies, Easiest way is add that folder to the Gimp plugins paths, however read the readme in the zip.
Works ok here Win7 64 bit (VM) / Gimp 2.8
Note: No good trying to update the filters, they are gone unless someone has a backup for gmic 1.6.9 updates file
EDIT: For a QT version this is the earliest I could find. A version 2.0
