===== Installation problems =====
==== Service doesn't start ====
  * The installer ran successfully, but you can't reach the UI with your web browser.

=== How to investigate ===
  * Open the services screen in windows task manager
  * Check that Pro.Monitor service is installed and running
  * If it is not running, you probably had problem during service installation.

=== How to fix ===
  * Open a windows shell and go to ''[ProMonitor install path]\bin''
  * execute: ''services.bat install ProMonitorTest''
  * If you see an error message relating ''JAVA_HOME'' env variable:
    * Check you installed only the java JRE and not JDK
    * Set ''JRE_HOME=[Java install path]'' in your environment variables (**Not adding the ''bin'' folder**), by Example: ''C:\Program_Files\Java\jre1.8.0_171''
    * Remove ''JAVA_HOME'' variable
    * Open a new windows shell and go to ''[ProMonitor install path]\bin''
    * Execute ''sc delete Pro_Monitor''
    * Execute ''services.bat install Pro_Monitor''
    * if the command is successfull, then the service can be installed correctly.
    * Execute ''sc delete Pro_Monitor'' to remove it again and let the installer do the job.
    * Uninstall ProMonitor by running the ''uninst000.exe'' file from Pro.Monitor install folder.
    * Execute the installer again, the service should be created correctly this time.
  * If you see an error saying "Problem finding JAVA":
    * Run the pro_monitorw.exe program from *bin* folder, Tomcat property screen will open.
    * Got to java section and check that Java Virtual Machine section is well configured: It must point to the **bin\server\jvm.dll** file

==== All connectors stay in UNKNOWN state ====
  * You can log in the server, but monitoring doesn't seem to work: Perhaps the worker cannot find java:
    * Remove folder C:\ProgramData\Oracle
    * Remove any java.exe or javaw.exe file in C:\Windows\system32 and C:\Windows\SysWOW64
