Thanks for this fast and helpfull answer!
Unfortunately nothing helped. First i tried the x64-DLL, then i removed NET completly with the cleanup-tool. After all I've reinstalled it and updated it - The Program don't start with any of the DLL.
When I install NET 2.0 it informs me that this is part of Windows 7 already.
But there are different behavoirs with the DLLs:
x86: Shows the Splash-Screen and then terminating with the info like above. Sometimes it opens around 10 empty windows, when it shows the error dialog.
x64: No Splash-Screen - it craches with this info: "System.BadImageFormatException" - maybe the DLL is defect?
When I remove both DLLs from the program folder i got the io-not-found-exception without splash screen.
I tried running with admin-rights and compatibilty mode, too.
Any further Ideas? =)

Some further infos:
I've downloaded the System.Data.SQLite from here:http://sqlite.phxsoftware.com/
When i run the test program, it crashes too. But there is a detailed error message:
System.Data.SQLite.SQLiteException: Unable to open the database file
bei System.Data.SQLite.SQLite3.Open(String strFilename, SQLiteOpenFlagsEnum flags, Int32 maxPoolSize, Boolean usePool)
