PROPER:
Release by other group contains old contents and have collision issue in the custom installer.

    -----------------------------------------------------------------------------

    Due to the change of iLok deal in iZotope products, we haven't released
    new products for years. That "AuthAssistant.exe" is dropped and all iLok API
    call is included in the plugin itself, which means emulator is not a possible
    attack anymore.

    Although cracking iZotope is not a difficult job, we took a time to make it
    "better" in many meanings, just install and enjoy :)

    - Simplified custom installer
    - Pre iLok Authorization without iLok driver
    - Seperate component installer (No installation collision like orignal)
    - No installation info disappearing like original
    - Better compression than original
    - Faster installation than original


    You CAN mix new R2R releases with others, but NOT RECOMMENDED, since new
    iZotope installer has some issues we listed above. You should install R2R
    releases only, to take the best advantage.

    If you want to clean up old iZotope releases before starting installing new
    R2R releases,

    1. Uninstall ALL iZotope products
    2. Delete RegKey HKCU\Software\iZotope
    3. Done, let's start clean iZotope life and
    Stay away from official installers.


    Because we don't use official installer nor iLok integration, we won't
    release minor change updates for iZotope products.

    v2.00 -> v2.01 - We take care
    v2.00 -> v2.00b - We won't because not affected

    In other words, you can ignore those official minor change if you use R2R
    releases. If updated is needed by minor changes, we take care in that case.
