After installation you will need to activate the software using your serial number. This requires an internet connection (software since 2014).
Once the serial number is used for activation, the program is registered uniquely to you under your MAGIX account. This allows you to use the free email support service (12 months). Serial numbers also help protect against software piracy, which ensures that we are able to continually provide our customers with an optimal price/performance ratio.
After initial activation you are able to use the software without a permanent internet connection!
