SIM Installation database error

[KorayAlkan]

Dear All,

I have a SIM installation problem. At "Database Configuration" section of the SIM installation we get "An unknown database error has occurred. 16". I cannot pass this screen.

Are there any people who have exprienced that problem?
SIM version= the version that in Smartstart 7.42

I think this may be because you have existing DB's there. Remove any SQL DB instances from old installations. If you are using SQL Desktop install Enterprise tools to remove DB's from SQL and delete the old MDB files as well.

I am installing clean install. MSDE was not installed before the SIM installation. I tred tree different servers. I am experiencing same problem. Strange thing is Database name is seen as "master"
