Dear All

ahm... i guess he has a different version of the website(with different contents) developed somewhere else and trying to install it  on the same version of the DNN perhaps? not sure.

Rasika, plz write the DNN version here. I would double check machine key (i know you did but just in case).

I would also try this: https://my.re-invent.com/helpdesk/KB/a210/how-do-i-reset-my-dotnetnuke-host-superuser-password.aspx

if you are simply changing the api and some modules then why do you have to reinstall the whole site - just update the changed files - I assume you are not changing the DB structure so you only need to over write the changed dll's and aspx files - this leaves all you content and user base intact.

This is the procedure that I use (my framework is not identical to dnn framework) I only have to upload the changes as I am not actually updating the dnn version. No matter which way you go you will still have to upload the changes to all clients any way - you could make that process automatic with an install program but you will still have to upload the changes and run the install on each client.

Basically you are updating the version on the client site (not the dnn version but your own) so just write an install script to do it . I assume that if you are changing the DB structure then you would have sql scripts to do this any way.

You could follow the auto module installation setup built into dnn - modify it so that if there is any thing in say install/updates directory then the site will automatically run them - in this case you would only have to upload the changes to each client and place them into the install/update directory - the scheduler would look after the rest.

Probably also a good idea to carry your changes thro to 4.9.2 and use that as your base framework rather then 4.8.0.
