Hi all! At first, thanks for the GREAT work in this topic! Here follows now a question regarding the support of WSUS Offline Update (for installing **Office** updates) under **Wine**. Is this technically possible? I have tried that with **MS Office 2010** and WSUS Offline Update 11.9.6 ESR and WSUS Offline Update 12.3.1 but both don't work. The Office 2010 updates were simply not installed in the Wine 8.5 prefix. After starting `UpdateInstaller.exe` and selecting "Start" the command prompt is opening and closing and no updates is applied. It is only possible to install manually the Office service pack but this can be done also without WSUS. :wink: My steps where as follow. I have collected all available Office 2010 updates under Windows 11 Home. This worked perfectly fine with both WSUS builds. But after copying the whole WSUS folder structure over into the Wine prefix the installation failed. Note, the corresponding Wine prefix contains a normal Office 2010 Home & Student version but it is **not activated**.
