Sophos Endpoint Agent blocks GIMP 3.0 RC1

it might just be that you're launching it from the browser download.  If you download the file, then in Explorer navigate to the file in your Downloads folder and run it, does it work? 

... and where do I find the correct download?

Not sure I understand.  I thought you were downloading a file via the browser and running it?

What I'm saying is, download the file via the browser.  Then navigate in Explorer to the file you have downloaded and run it.  I.e. don't run it from the browser download manager.  Does that help?

Oh... right, now I get it! Sorry
I did as you suggested right the first time
Rutvika Chavda told me to try and install "MR" Version of some Sophos stuff. That is the download I asked for ;)
