O where did you install it?I believe the Gimp-2.7.3 version has its own .gimp-2.7 folder.
You should find the filter after install under Layer/Clone Layer Tool
Note - you have to have an new document opened first to be able to use the filter.
I put the install file in lib\gimp\2.0\plug-ins as instructed over at the Registry. I have been posting over there too.
I used the 64-bit compilation as I have Win7 64-bit on my laptop.
I'm registered over there with two different names. I was finally able to get the Oregonian registration to work, but I'm there as, "zarnad," too.
It did open the file and there's an exe file in the plug-ins folder. If I double click it it says libgimp-2.0-0.dll is missing, but I can see that file in the lib folder. When I start gimp, that exe file should make the plug-in work in gimp.http://registry.gimp.org/node/25422
