The install finished successfully, but the IBM providers do not show up in Visual Studio 2010 or 2012. Also when installing the Visual Studio tools it says it cannot find those providers. It does show up as being installed in the installed programs list as well...
Could you please give us testconn40 output? testconn40 would be in <product install directory\bin.
testconn40 "Server=<ipconfig/machine name>:<port no.>;Database=<databasename>;uid=<userid>;pwd=<password>"
Also please provide us with screenshot of the error and commontoolreg*.log in %APPDATA%\IBM\vsnet2010
