Leu <kle(a)bluewin.ch> --- A new little update to this interesting topic. I can confirm this bug. It is 100% reproducible on more recent multi-core based systems running Kubuntu 20.04 LTS and Wine 6.0.1 stable. Despite many many attempts I was NOT able to install Office 2010 Home and Student (incl. SP1) at a new AMD Ryzen 7 5700U based PC. I really have tried EVERYTHING but it didn't work, the installer always crashed at the 50% mark. I decided then to try it at an old single-core AMD Athlon II Neo K145 based Netbook. And to my big surprise the installation worked perfectly well right from the first time. I deleted the prefix and started the installation a second time. It worked again absolutely error free! I repeated this a third and fourth time, - always without any issue. So I am now really baffled, the installation of Office 2010 works 100% reliable at a single-core Netbook while it fails 100% at a modern 8-Core Ryzen based PC. Something really strange is going on here... ;-) Finally, I copied the "preinstalled" Wine prefix over from the Netbook to the Ryzen PC. The installation of the MS Office 2010 Service Pack 2 went flawlessly, this also reinstalled the missing Start Menu entries. All Office 2010 Home and Student applications are running great. I have used the following winetricks parameters: Before the installation: winetricks -q mfc100 winetricks -q msxml6 After the installation: winetricks -q riched20 Optional, maybe only sometimes needed (not used at the "Ryzen" Wine prefix): winetricks -q gdiplus I also applied the "Office 2013 black window" registry tweak (before the installation): Add a new "Direct3D" key in "HKCU\Software\Wine\" with dword "MaxVersionGL" and value "30002" (hexa). It would be nice if someone can explain here how I can limit in Wine the number of CPU cores to one single? Maybe this would allow the installation of Office 2010 also on modern multi-core based systems. https://appdb.winehq.org/objectManager.php?sClass=version&iId=17336&iTesting... -- Do not reply to this email, post in Bugzilla using the above URL to reply.
