Yes, it looks like you had two machines and one of them was fine with the update, the other had this error; at the time you copied the installed content from one to the other.

Yes, the installer is the same. It detects whether it's installed or not to determine whether to offer an update or new install.

When you say "code history", are you referring to changes to the vortex scripts? If you've made script
modifications, then those reside in texis\scripts\webinator\

Depending on where you kept your profile databases, keeping the things inside the "texis" directory and texis.ini should be enough.
If your existing version is recent enough, you can go to Maintenance -> Save Webinator Settings to make a backup of your config; then you could restore that after the install without needing to muck around with copying files.
