Can't launch Jira Core.

[Саша Николваев]

I’m unable to launch Jira Core. After installation, the installer reports that everything is fine and opens the localhost page, but an error is displayed in the browser window. When I run start-jira.bat, the following message is displayed.

Environment variables are set (JAVA_HOME, JDK_HOME, JIRA_HOME). I have installed and uninstalled Jira and JDK many times, I have installed different versions, but none of this helped.
Also I set for ignore_jvm_version variable "true" because I thought that if the java -version command works correctly it would help. After that this error appeared:

(ru) Непредвиденное появление: 9
(en) Unexpected appearance: 9

I saw the same issue here: https://community.atlassian.com/t5/Jira-questions/JIR..
But it didn’t help.

I ask you to help me with these problems.

One of the .bat files used in starting it is broken, you'll need to debug that.  You need to look for the line that is throwing "

find: /V: No such file or directory

and work out why that message is being thrown.  At a guess, it is probably that a tool on your machine has a "find" tool in it which has been included in the default environment path, so it gets run instead of the windows native "find" command and the batch file does not know that the tool has done this or that the parameters for it are different.
