If I bought the retail version, is the serial key stored in my redist folder or DVD ?

That's odd. Maybe check your email?

Indeed it is.

Well, I've written to the retailer's helpdesk e-mail. We'll probably just have to wait and see.

Bottom line : I'm not sure whether the game even asked me for a serial code when I installed it the first time a year and a half ago. The logical answer would be yes, but truth be told, it's been so long I myself don't remember.

What I worry about the most is that if I uninstall Amnesia now completely, I might not even be able to reinstall the vanilla version. There's still one last hope : I could return my computer settings to how they were prior to when I installed the DLC. That could help fixing the Amnesia install, eliminating the DLC files and making me able to play at least the vanilla game in case I might never get the DLC working.

This is what happens when retailers and publishers don't communicate well together. I hate it when retailers make up incompatable new serials, if that's the case.

But I'll wait for the company helpdesk's answer first. If that fails, then I'll try plan B - reverting the settings.

He got it through retail, which means in a store, not online. Therefore, there'd be no email.

Precisely.

EDIT: Go to "C:/Users/YOURUSERNAME/My Documents/Amnesia" And check if there's a file labelled "installkey". If it's there, open it in notepad and it should have your serial number inside. Copy and paste it where specified for Justine.

Good idea, but it unfortunately didn't help. I didn't find anything like that in there. Just the usual player profile folder, saves and configs.
