No matter what I do I cannot find it, the only thing I can find is the XLMiner Analysis Toolpack. Ive googled everything to try to get it for my school assignment but I cannot find it. Please help!
We have a user that uses only the web version of the apps even though they can install them locally. I have been unable to find the 'Analysis Toolpak' for Excel anywhere in all the 365 admin centers. I have found deployable add-ins like XLMiner that I could make available but I was wondering if the OG was available and I am just looking in the wrong spot.
UPDATE: the organization has disabled access to the office store, but I couldn't find it to add so they could have it despite not having access to store
