The scenario is correct. I do use multi-tenant and I use the demo key. Yesterday, since I couldn't find a solution I tried reinstalling multitenant.. however I started getting a very similar error when trying to activate the demo key, even when udating to SP5. I tried a couple more times, and I could get it activated with SP5. I haven't made any more changes until I could hear back from this thread.
As I understand it right now, there's two ways to make it work:
1.- Modify a registry setting. (I can do this if that's the only option.. and it is a fairly simple change).
2.- Reinstalling multitenant. As far as this option, how is that supposed to be done?
1.- Do I backup the configuration, uninstall, reinstall, create a basic configuration, update the system to SP6, activate and then do a restore of my actual configuration? (I already tried this, and I got the same error when activating a basic configuration (through the wizard) while being on SP6.
2.- Do I backup the configuration, uninstall, reinstall, RESTORE the configuration, and then update to SP6 and try activating?
On the other side, is there a more recent multitenant installer that already includes SP6?
Thanks for your help!
