I can't install predictive tools on all versions of alteryx, when I try to install the following error appears: Alteryx is not installed
Is your Alteryx Designer Admin or non-Admin? It looks like the Predictive Tools you're installing are non-Admin (User), so I'm wondering if your Designer version is Admin. I don't know all the ins and outs for how the Admin and non-Admin versions interact, but I'm thinking a mismatch could be your issue.
Apologies for asking what's maybe a silly question - have you already installed Designer? I see that you downloaded both today (Designer and Predictive Tools) so I want to make sure you already installed Designer before trying to install Predictive Tools.
If you have, then I'm sorry, I'm out of ideas, other than the usual "restart your computer and try again" suggestion
If no one here has any ideas, you can create an Alteryx Support case at the Case Portal - https://my.alteryx.com/cases
Yes, Designer is installed :)
