I updated from Crossover 18.1.0 to the new 20 today. It didn't appear to update, so I reverted back to 18.1.0. I previously had MS Office 13 installed and working fine. During the process of upgrading Crossover and then downgrading I also deleted the bottle. I didn't think much of it since I knew I had no trouble installing Office a couple years ago.
Now I can't get MS Office 2013 to install. It starts the installation, installs a bunch of fonts and the XML Parser, then I get an MS Office error screen saying:
We're sorry, but we can't verify the signature of files required to install your Office product
There are no icons in the Crossover dashboard (except the Run Command).
I think I am connected to the internet, since it did manage to get the fonts and the parser. The MS Office install file is generated as a small 1 MB file with a licence certificate I have, so I don't think there's much in it, thus I'm pretty sure the parts it did get (fonts, parser) it downloaded.
There are still some files on my computer from that original installation - not sure if the bottle actually might still exist. If it does, what files am I looking for, and if I happen to have the right ones to get it to work again, how do I get them to be recognized in Crossover.
I have tried creating several different types of bottles and I get the same type of partial installation and error.
I've tried Run Command on the exe file I have, and it just runs for a few minutes, then comes up again with the same Office error I posted above.
Any help in getting this back up and running would be appreciated.
