"Some physical copies of the PC version of Rocksmith are encountering problems during installation," the post reads. "We apologize for the inconvience caused and will provide any affected customers with the ‘Guitarcade timesaver,' which gives players instant access to all the Rocksmith mini-games."
Customers who did not get a code with their game will have to submit a claim to Ubisoft via their online support. The form requires both the store details and a "clear digital image" of the buyer's receipt. According to Kotaku, codes are beginning to arrive to those who have filed claims.
Rocksmith for the PC released in Europe on Oct. 18.
