Hi Mark, My Stacks 3.6.6 is not installing either.
I’m having the same problem installing Stacks 3.5
I am using Rapidweaver 6 along with Stack 3
I bought Rapidweaver 6 many years ago, along with Stack 3
My Mac Pro is OS X 10.11.6 El Capitan
All I want to do is update my already installed Stacks 3.
I want to buy Joe Workman’s Footnotes. It requires Stacks 3.5+
I just need to update my Stacks 3 so it’s current Stacks 3.6.6
Like Mr Spaulding, I get the same message
“This stack is not currently installed. You need to reinstall it to use it.”
I contacted Yourhead Support, request #6544. March 7, 2019
I assumed Yourhead could tell me how to update my older Stacks 3
I will cc Mr Isaiah Carew Addon Developer and Mr Jan Fuellemann
Then there is YourHead News, APPS, STACKS, AND PLUGINS
Stacks 3.5 August 09, 2017 <<http://blog.yourhead.com/stacks-3-5/>>
It appears to be a free download and install.
What you’re saying here is that there is a STACK that is missing, not the Stacks plugin. The Stacks plugin allows you to use stacks from different developers. If you look in the inspector, it should give you an idea of which stack is missing.
I would like to take this opportunity to thank Doug a.k.a. teeters and Neil UK for their help.
Whenever I run into a problem, generally, the enemy is me!
I had the same problem after a different program that was installing glitched something on my iMac. Stacks told me to enter my key or purchase the product. Yourhead.com didn’t have an answer as to why it was happening, and even gave me a different key to enter. Reinstalling RW didn’t help. What I had to do is go through the Library folders and delete EVERYTHING that had reference to Rapidweaver files. I then reinstalled RW and Stacks 3.5 with resulting success. Some plist file was possibly corrupted. It was a frustrating and strange experience, but have not had any problems over the past 8 months or so.
