I have faced the same (Windows 7 upgraded to Windows 10 adopter) issue and I have been patiently waiting for the fix just like the others on this forum. I must have tried the manual fix a few times but it doesn’t work. It gives me the dreaded message about the missing msihelper.dll file. I cannot uninstall the program from the control panel due to the same missing dll error.
If there is a custom installer file to fix this error I would love to have it.
