.Net Framework Version

[kenb2004]

I had a problem installing a .Net Framework 1.1 SP Security update so I contacted Microsoft and in order to resolve my issue they uninstalled ALL my .Net Framework installations and updates and installed ONE complete version supposedly including all versions through .Net Framework 3.5. However now Ninja will not launch. I get a Error message saying "Unable to connect to database 'Provider=Microsoft.Jet.OLEDB;User ID=Admin;Data Source=C:\Documents.....db\NinjaTrader.mdb ObjectSpace: Connection String is Invalid - Could not load file or assembley 'System.EnterpriseServices.Wrapper.dll or one of its dependencies. The system cannot find the file specified.

What version of .Net Framework is required to run NinjaTrader and do you think this Error is related?
Thanks

Hi Ken,

NinjaTrader requires .net 2.0, which is included in all 3.5 installation.

The message you're receiving is typical of a .net issue. In these cases we normally suggest repairing or reinstalling with this version here:
