Hi there ! I've activated my ProPlus via valid Beta old MAK tokens. Unfortunatelly, the beta expired today and the activation invalidated. Now, I have a bunch of retail MAK keys I want to try. Office Toolkit 2.0 says The Software Licensing Service reported that the license is not installed (Key management) and Office self won't let me to the Change product key dialog since it doesnot let me to UI. I need to know how to invoke Change product key dialog, or change it by some of known toolkits. Thanks for any working solutions, hopefully my Office will be working again soon.
