I try to reproduce the error but on a new install with a clean database the error will not occur because the code is not executed. The only possiblity is that you run the install wizard before and the database you use is not empty.

bbobb: what might the solution to that be?

Most probaly, this piece of code causes the problem. At least, after this it will be clear where exactly the problem is.

if (prevVersion < 49)
{
// Reset The UserBox Template
this.Get<YafBoardSettings>().UserBox = Constants.UserBox.DisplayTemplateDefault;


((YafLoadBoardSettings)this.Get<YafBoardSettings>()).SaveRegistry();
}

what is
select * from yaf_registry where name = ' versionname' ?
or execute this: select * from registry_list('versionname')
You should set your db prefixes into the object names. like dbo.yaf_registry list.

Watcha:
I did a clean install with a newly deployed database; the install routine worked until hitting:

Exception Details: System.InvalidCastException: Unable to cast object of type 'YAF.Classes.YafBoardSettings' to type 'YAF.Core.YafLoadBoardSettings'

I ran the install routine a second (third etc.) time with a partially populated database, and it throws:

There is already an object named 'yaf_drop_defaultconstraint_oncolumn' in the database.

Which can be expected as on error or install it doesnt roll back, delete previous, or check for partaially installed tables.

bbobb:
Sorry, I'm too much of a YAF-noob to spot why that is an error, where to find it, and what to change it to. Can you be a bit more specific of what I need to copy and paste to where? Also my C# isn't that good; it isnt my first language.

If it's saying there already is an object there, that would somehow mean it wasn't a completely fresh install. I'm not familiar with Azure setups, but I would use a fresh new database with a name I haven't chosen before and give it that a try.

You need to run the sql script I have posted. If something can be fixed it will be fixed without you. It's just required to spot the place, because it normally can't be reproduced.

Ok I updated the downloads for the install packages again, now the installation should work.

---

I know I'm 3 years late, but I'm having the exact same issue. Completing the install wizard (clicking next and waiting for it to install) results in either Unable to cast object of type 'YAF.Classes.YafBoardSettings' to type 'YAF.Core.YafLoadBoardSettings' or No candidates for a guest were found for the board 1.. Stack traces are same as posted by OP.

I think i found the problem, can you re-download the packages and try again. You need to clear the database!

Thank you for your fast response! I get the same issue during the installation, unfortunately. Every time the install fails I delete the database resource in Azure and create a new.

If it's of any relevance I am publishing to my Azure app service from Visual Studio (can't connect via FTP) using the Connected Services feature. I've set up an ASP.NET Web Application (C#) solution and added the .zip content to a project in that solution. I don't know if this affects the installation in any way...

Did you download the install package?

---

Yes, from the link you provided

Atleast on my tests it works as expected. Are you using the recommended azure web.config?

---

I'm having the same problem

I'm having the same problem

Did you install the latest version 2.30? The problem should be fixed.
