I'm installing mediawiki in IIS on Server 2012 R2. I am using SQL Server.
After completing the installation form and starting the install the process fails with Could not create a new page. It already exists.
If I choose back I need to drop and remake the database so that the creating tables routine doesn't fail, but if this is done the install stops at the same point with the above error. This is the same if I choose to restart installation.
I have fully deleted mediawiki and extracted a new copy to the folder IIS expects it to be in and I leave the web.config file. After this i get the same error as above.
There isn't a localsettings.php file anywhere other than the ..\extensions\MultimediaViewer\tests\browser\ one. It appears that no additional files or folders have been created as they have the same number as a newly extracted install (+1 for the web.config file)
I'd appreciate any help or advice. Thank you!
