ATTENTION: From Spire.Doc v3.6.0, the registeration way have been changed. We deprecated the old username-key registeration method and use a new license file to instead. You could get more information about the license file from: http://www.e-iceblue.com/Knowledgebase/Licensing/documentation-licensing.html. If you purchased an old version earlier than v3.6.0 and you want to use the new version, please use the email address, to which we previously sent your register key, to send me a mail to acquire a new license file.
