John, does Skype Portable handle upgrades well?
I'm concerned b/c Skype Portable is an online installer.
Also does this version address the /secondary command line issue - allowing for multiple instances of Skype to be opened?
Looks like there's an upgrade routine.
Yes, Skype Portable handles upgrades like all PortableApps.com Format apps. What we call in-place upgrades (just install the new one over the old one). All our online installers handle it just as well. All data is preserved. Plugins and addons in supported locations are preserved as well.
No, we don't currently support the /secondary switch due to a bug within Skype itself. Even in /removable mode, your Skype chat logs are stored in %APPDATA%. So, if two copies of Skype are running, both get stored there, and we're unable to differentiate the portable logs from the local ones. If there were a better way to handle it, I'd definitely look into it.
