As per my understanding, you are also not able to connect to the Virtual DataPort server using either the Web Design Studio or the Virtual DataPort Administration Tool. In that case, I would suggest to check the VDP log files which are: `<DENODO_HOME>\logs\vdp\vdp.log` and `<DENODO_HOME>\logs\vdp-admin\vdp-admin.log`, and further inspect the whole logs for any errors. The “‘admin’ database not found” error can be a result of other underlying errors.
Furthermore, you can try to troubleshoot your installation by running the installer in debug mode so you can inspect the installation logs for any issues. You can refer to documentation [Troubleshooting the Denodo Platform Installer](https://community.denodo.com/docs/html/browse/8.0/en/platform/installation/appendix/troubleshooting_the_installer/troubleshooting_the_installer) for a guide on how to do this.
Hope this helps!
