Is it possible to install both 7.x and 8.x versions of Jaikoz in one OS?
Reason: the Jaikoz version 7.11 gives better results than 8.x in relation to several songs with different artists in one folder (Top 100)
Two installations of Jaikoz?
Not at all easily because when you install Jaikoz 8 it will update your preferences (that are in a shared location) to the Jaikoz 8 version, which will then be incompatible with Jaikoz 7,
Would be better if you could raise jira issue with full details so that I can improve Jaikoz 8 to resolve issues such as this.
