I’d try starting the platform by double-clicking the *denodo_platform.bat* file, as that is also a valid way of starting the Denodo Control Centre.
If that does not work, you can also try from the command line, which may give you some feedback as to why the platform isn’t starting. To do this, open the “Command Prompt” tool in Windows, and enter the following, replacing <DENODO_HOME> with your Denodo installation location:
> cd <DENODO_HOME>\bin
If this still does not give you any feedback, I’d take a look at the vdp.log file at <DENODO_HOME>\logs\vdp\vdp.log
I hope this helps!
