Hey Bert,
I ran into the same issue when I tried to install AC 11.1.2 on a new PC in our office yesterday ("...failure occurred attempting to cache a file...msxml.msi").
Where can I obtain msxml.msi? I tried looking on other PCs in our office, but I couldn't find it. (I'm presuming it's an install file that got deleted after previous AC version installs.) I also looked online, but there are numerous versions available for download, and I don't know which is the proper one.
Any help/guidance is appreciated!
Thanks,
Dana
