Thanks for looking into it... but still not working.

I believe your error message refers to the old scrolling plugin problem, if I remember correctly. Go to your Plugins folder and remove "script-fu", then try it again. If it works correctly, you'll need to get the revised "script-fu-210" to replace it.

Here's the version I have in Linux, not sure if it works in windows or not.

Tried everything... also on clean installation... keep giving error.I give up.Thanks everyone for thinking along!

Hi Ineke! Let's try what Racer-x said.
1. Download this zip folder "script-fu2.10 64bit" Windows version and extract the plugin.
2. Go to you GIMP 2 proram main files: C:\Program Files\GIMP 2\lib\gimp\2.0\plug-ins\script-fu, and place the one you have here, (Cut and Paste) on your desktop (Do not deleted yet)
3. Place the extracted version on the same directory of the original one: C:\Program Files\GIMP 2\lib\gimp\2.0\plug-ins\script-fu
4. Re-start GIMP and try the Bubbles script again,

Still works for me; had to try something (long dry spell) and saw this thread. lol

Of course, I added some convolution steps with original image Grain merge (and some additionaly stuff) to the result.

The original for gimp-2.10 still works for me as well. Although i do get a dll warning but i believe it's because i use G'MIC version 3.2.0.

It is working alright for me, too.
No warning either.

I reinstalled Gimp and G'mic and now it works! Thanks to everyone!
