By default, Connect will automatically download and extract the update. After entering your download code, click Download. Connect will ask you for a location. Pick the collection folder, which is the folder where the Documentation, Instruments and Samples folder, etc. are located. Connect will then download and extract the update into that folder.
Collection Folder (here BST)
If for some reason you want to download and extract manually, you can use the Manual Links as detailed in the Installation Guide. When extracting, make sure to extract all downloaded files directly into the collection folder, overwriting old files when prompted. Do not install into any subfolder; do not create a new folder for the update and do not change the folder structure in any way.
To make sure the update has correctly installed, open any patch. The InfoView will show the Capsule version number as well as the collection version number. Check with the Current Versions and make sure the Capsule version and collection version are correct. You can also browse the Folder Structures section to make sure everything is correct.
