I run 2.1 portably and will continue to do so until 3.0 is available, because there are simply too many bugs and instabilities in 2.2.1 for my purposes.
But something is screwy with Writer all of a sudden---it won't open files and thinks everything needs to be recovered, and wants me to choose a file filter--- so, after testing with a standard installation of 2.2.1 to make sure there was nothing actually wrong with the files, it appears that I need a fresh copy of the portable version.
I see that older versions are not available through the PortableApps site (or at least, not where I could find them) and I searched SourceForge.net and the Internet without luck. (SourceForge returned over 1500 hits and I searched the first ten pages or so, but with no luck... and most of those had nothing to do with the application itself.)
If you can point me to a 2.1 download, I'd be deeply grateful.
