If I face this issue, I would try launching the Denodo Platform by executing the **vdpadmin.bat** (for windows) under the <DENODO_HOME>/bin directory with the **administrator** privileges so that I could see the error which is causing this.
Also, I would ensure the [**JAVA_HOME**](https://community.denodo.com/docs/html/browse/latest/platform/installation/preinstallation_tasks/configuring_the_server_for_the_denodo_platform/configuring_the_server_for_the_denodo_platform#check-the-path-environment-variable-windows) environment variable is properly set to "<DENODO_HOME>/jre/bin". In case you have a separate Java installation, you could point JAVA_HOME to "<JAVA_DIRECTORY>/jre/bin"
You can take a look at the [**Launching the Denodo Platform Control Center**](https://community.denodo.com/docs/html/browse/latest/platform/installation/denodo_platform_control_center/launching_the_denodo_platform_control_center/launching_the_denodo_platform_control_center) section of the Denodo Platform Installation Guide.
If the error persists, you can check the **denodo-launcher.log** file located in the "<DENODO_HOME>/logs/launcher" directory for more information.
Hope this helps!
