Product Activation steam error

i just bought a fresh unpacked Copy of Homeworld: Remastered Collection pol/cze/slk/hun at my local shop - original company, not some second-hand.
And when i want to install it i write code that was inside in book and i saw message:
“Please first activate the original game. The product code you’ve entered requires ownership of another product before activation. etc.”
There is no “Invalid Product Code” message.
I dont know what to do, Who should i write in this case ( im from poland), who can help me? or maybe i was framed or fooled :frowning:
sorry for my bad english,
