Some manufacturers in the updatemanager are ‘locked’. To get access, you have to get permission from the manufacturer. Contact your agent or wholesaler: he or she will get the permission from the manufacturer. Communicate your ViSoft Customer ID to the manufacturer and ViSoft. You can find your Customer ID in ViSoft under Help > Registration info. 

After receiving the permission forward it to ENTERMAIL to get access. The mail of the manufacturer needs to contain their logo.

When you have received the green light, download the brand with a rightclick > Start download immediately.
