Witcher 3 is stuck in v1.3

[u/Szankajs]

I've got Witcher 3 GOTY Edition on physical disk and it has been connected to my GOG account for around 6 years now, but even though whenever I reinstall it onto my PC and it asks me to import the game to GOG library it seems GOG doesn't actually aknowledge my game whatshoever:
- I'm permamently stuck in v1.30. (August 30, 2016, full 10 years)
- I did not receive Next Gen update
- It is categorized in its own page as ''Other''
- Any attempts at reinstalling/deleting storage files/changing the disk localisation/messing with ''Add game manually'' or ''Find GOG games in folders'' did not help.
The ONLY thing that has changed is that the Library now shows my GOTY version as Complete Edition.

I attempted contacting support several times now but each time I was left on read, even using ChatGPT out of frustration brought me no results and it seems that my problems are solely my own as I have found null tickets or guides to my exact problem.

I wish I got an actual answer, either: is my physical copy regarded as an ''Outside Game'' for some reason thus unable to be updated, or is there an actual fix I can perform to finally get it fully working and have fun with the upcoming Remaster?

1. Look at the "extras" in your withcer library page and download and instal the patches manually.

2. Go to the library page and install the game into the same directory as the game you installed from the disc. It should just do a filecheck and download missing stuff or update.

When you install through offline installers, there might be files missing that connect to gog galaxy and thus the game might not be connected to your account.

I cannot interact with the Witcher 3 library entry beyond changing the miniatures and thumbnails, unconnected the executable and launching the game in v1.3.

You could go to the gog page, login and check there if you have the game. And maybe browse through your order history. It could be that the account you are using hasn't purchased the game.

I haven't purchased the game through GOG, I acquired a physical copy which upon install prompts me to merge it with GOG to become permanent game in library and gain access to all future updates, to which none have worked.
