Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I tried the install of SP2 - 5 times. It failed everytime with error 80070643. I'm running Windows 7 - 64 bit; and I think I am running Windows Office 32-bit. I tried the fixes Microsoft online support pointed me to. That is: Repair MSI with Fix it - which said it did. And repair .net Framework 4 Client Profile.
All previous updates installed successfully for Windows Office 2010.
I'll try your solution.
