How to Install a Second Version of Isadora

(Click here to jump to a discussion of this Knowledge Base article in the TroikaTronix Forum.)

It is possible to have more than one version of Isadora installed on the same computer; instructions for both Macintosh and Windows can be found below.

IMPORTANT NOTE: File Formats

At certain points in Isadora’s history, the file format was changed. A newer version of Isadora can always open a file saved with an older version. But, if you save a file in the new format, the older version will no longer be able to open that file.

The last file format change was before v1.3.0f24. So if you’re working with that version or later you don’t have to worry. But if you are going between a version before 1.3.0f24 and a version after that, you need to take this warning into consideration.

Installing a Second Version: Macintosh

  1. Go to the existing Isadora application and rename it. We recommend adding the version number to the name, as seen in the “Get Info” window for the application. (For example, changing “Isadora” to “Isadora 1.3.0f24″)
  2. Install the new version of Isadora. Again, to keep things very clear, we recommend adding the version number to the name.
  3. Drag both applications to the Dock for easy access.
  4. When you have two versions installed, it is a not a good idea to double-click your Isadora document (.izz file) because you cannot be sure which version of Isadora will open. If you followed step 3 above, then you can drag the .izz file to the specific application you want to use in the Dock. Otherwise, find the application you wish to use in the Finder and drop the .izz file on to it.

Installing a Second Version: Windows

  1. In Windows Explorer, navigate to the folder that contains the Isadora installation (usually at C:\Program Files (x86)\).
  2. Right-click the Isadora folder, and then choose Copy
  3. Right-click an empty space within the Program Files folder, and then choose Paste.
  4. We suggest that you rename the copied folder to “Isadora XXX” where XXX is the version number of the program.
  5. Open the copied Isadora folder. Then, right-click the Isadora application choose Create Shortcut. Drag the new shortcut to an open area on the desktop. Again, we suggest you rename the shortcut to include the version number of Isadora.
  6. Uninstall Isadora. (Open Programs and Features by clicking the Start button, clicking Control Panel, clicking Programs, and then clicking Programs and Features. From the list in this, choose Isadora and then click the Uninstall button.) The old version will be deleted, but the folder you copied in step 3 will remain.
  7. Install the new version.
  8. To open a file in the new version, just double-click your .izz file or choose the Isadora application from the Start menu. To use the old version, double-click the shortcut you created on your desktop or drag your .izz file to that shortcut.
