I am upgrading to SQL 2008. In development, I have SSIS 2005 on the default instance of a server and SSIS 2008 on a named instance. Windows Standard Server 2003 x64 SP2, SQL Server 2005 x64 SP2 and SQL Server 2008 x64.
In VS 2008, I created a package to send a test email and had it create a deployment manifest file. When I run it, I get the following result:
Unexpected error occurred. (Package Installation Wizard)
Unable to find an entry point named 'DTSSKUIsWKGorUnder' in DLL 'dts'. (DTSInstall)
at Microsoft.SqlServer.Dts.Deployment.PackageInstaller.Main(String args)
I found that someone else had submitted this same error with regard to accessing the data profiling visualization, but my situation doesn't match that one.
