Buyer and Seller are located in different countries that have adopted the CISG. Buyer purchases a software package online that immediately downloads and renders a particular hardware operational (but has no express warranty). After the software is completely downloaded, the program does not function correctly (due to incompatibility with Buyer’s computer configuration). Buyer alleges that it was Seller’s responsibility to specify the required configuration for the program to work. Seller alleges that it was Buyer’s responsibility to check whether his computer was correctly configured for the program. Who do you think is correct? Discuss.
