Typically, if the plugin's version is relayed as a roman numeral (ex. Colorista III, Denoiser II), the plugin cannot read its previous version's information*.

Otherwise, if the plugin version is relayed as a digit (ie. Looks 4, Form 3), then it can open previous versions of itself.

Examples:

• Colorista III cannot read Colorista II plugin information.
• Looks 3 can read Looks 2 plugin information.
• Denoiser III can't read Denoiser II plugin information.
• Mojo II can't read Mojo 2 information.

* Exceptions:

• Mir 3 can't read Mir 2 plugin information
• Primatte 6 can't read Primatte 5 plugin information.

When a product can't read its previous version's information, it will install alongside its previous version and not overwrite it.

When a plugin can read its previous versions information, it will install over its previous version.

Examples:

• Colorista IV can get installed alongside Colorista III.
• Looks 3 overwrites Looks 2.
