The XLC software is the same for both XLC Pro and XLC Ed subsribers. When XLC is first installed it will be automatically configured in the XLC Ed mode (with all its restrictions). If you have an active XLC Pro subscription a software release key, unique to each user, allows you to switch on full XLC Pro functionality.

Follow these instructions to configure XLC in the XLC Pro mode.

1. Log into the site using your username and password.
2. On the Member Login Menu click on the 'My Subscriptions' link.
3. Select the 'XLC Release Code' tab on this link.
4. Click the 'Send Release code' button and it will be emailed to your registered email address. Note: You will need a new release code when you have renewed your subscription.
5. Now open Excel and click on the "About XLC and settings" button on the XLC toolbar. Enter your username and XLC release code here. Save settings and you are configured in XLC Pro mode. Take care to copy and paste your username from the member login menu because it is case sensitive!
6. On the XLC toolbar press "Redraw all worksheet equations" and all the equations are redrawn without any "Non-commercial use." watermarks or hyperlinks to the ExcelCalcs site.
