Either the yasoon tab does not appear, ribbons do not update correctly or yasoon does not launch at all.
Prerequisites
This solution only works if you had a newer Outlook version installed (e.g. a test or trial version of Outlook 2013) and uninstalled it to revert to 2010. If this does not apply to you, please don't use this guide.
The Outlook uninstaller forgets to clean up some technical keys in the windows registry, which need to be removed manually.
Solution
Please open the Windows Registry Editor. This can vary depending on your Windows version. In the latest Windows 7 and 8 you can just open the start menu and search for "regedit". If this is not available, use Start -> Run and enter "regedit". (without " in both cases)
Caution You are working with the Windows registry. Invalid changes can lead to serious damage on your Office or Windows installation. Please read the instructions carefully and in case you are unsure, send your questions to our support team: contact@yasoon.de
Step 1: Check TypeLib Version
- Navigate to "HKEY_CLASSES_ROOT\Interface"
- Use the shortcut Ctrl + F to search for the key {00063001-0000-0000-C000-000000000046}
- Make sure you are at the following location: "HKEY_CLASSES_ROOT\Interface\{00063001-0000-0000-C000-000000000046}"
OR
"HKEY_CLASSES_ROOT\Wow6432Node\Interface\{00063001-0000-0000-C000-000000000046}". - If not, press F3 to get further results.
- There you'll find a subfolder "TypeLib". Make sure the Default key is {00062FFF-0000-0000-C000-000000000046}
Make sure the Version key matches your current Outlook Version.
