Try this.
Installing msinet.ocx is not the end of the process.
You must register it using "Regsvr32"
Regsvr32 [/u] [/s] <OCX file name or route> (also valid for dll files)
In your case:
Click on start and in the start search bar type cmd, right click on the command prompt icon in the programs area and then click on run as administrator.
At the command prompt type regserv32 msinet.ocx and then press enter.

Good luck.
