This morning I try to install and activate the Fences 3 and Groupy on my working VM, for security issue its offline from the internet. Unsurprisingly, I failed to activate that 2 software, but I saw there was an offline activation option for each.

Then I generated the request files, 'fences.req' and 'groupy.req' respectively. Then I followed the instruction of 2 software, both of them lead to the link activate.stardock.com, where only the Fences 3's activating windows showed up.

I submitted that 2 files one-by-one. A 'fences.resp' file is successfully generated while an error showed up when I submitting 'groupy.req', and I quote The product does not exist or is invalid. (1004).
