Office applications refusing to open while running SuperNova

This issue is currently under inevstigation and we are expecting a fix in the next release of SuperNova, 25.05.

If you find that Office apps such as Word, Outlook, Excel and PowerPoint are no longer opening while using SuperNova, try the following steps:

Switching to the Monthly Enterprise channel

By changing your Office 365 to operate on a "Monthly Enterprise" channel you will ensure that changes are delivered slower to your Office applications.  This delayed delivery of updates ensures that there is a greater time for Office update related issues to be resolved before they reach your machine.

For more information on how to change to the monthly enterprise channel you can check Microsoft resources like the ones below:

Alternative workaround 

If you are not able to change your Office channel/build the following workaround can also be implemented.  Please be aware that this workaround will remove TrueFonts support in the office applications it is applied to until the changes are reverted.

Disclaimer: Dolphin Computer Access Ltd. cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Before attempting the following, create a backup copy of your Windows Registry and a system restore point. Failure to do this may result in a non-recoverable system.

Add the following registry entries for each of the applications affected (winword.exe, outlook.exe, excel.exe, powrpnt.exe), replacing *process name* with application exe affected:

[HKEY_LOCAL_MACHINE\SOFTWARE\Dolphin\dol_hook]

[HKEY_LOCAL_MACHINE\SOFTWARE\Dolphin\dol_hook\*process name*]
"functions"=dword:00000000
"interfaces"=dword:00000000
"process"=dword:00000000

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Dolphin\dol_hook]

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Dolphin\dol_hook\*process name*]
"functions"=dword:00000000
"interfaces"=dword:00000000
"process"=dword:00000000

If you would like to restore TrueFonts support once you have installed an update to SuperNova please delete the registry keys that you created and restart SuperNova.
