2nd Jira instance throwing error Setup: JIRA can't create a lock for your jira.home directory why?

Question

I have installed 2nd Jira instance on same VM with different Atlassian folder name as

C:\program files\ atlassian (Project name)\......   and different ports (other than default).

Problem:

when I hit its login url , its throws error as '

Setup: JIRA can't create a lock for your jira.home directory

Your jira.home directory C:\Program Files\Atlassian Ashion\Application Data\JIRA can only be used by one running JIRA instance. This instance needs to create a lock to make sure another instance can't access the jira.home directory. Ensure JIRA has read and write access to the jira.home directory.
Review our documentation for more information on setting your JIRA home.

not able to run both instances at the same time. please suggest the workaround.

Ok, so now your start up scripts are damaged, or you're using the wrong thing to try to start it.

I am not sure how else to explain "start clean", but I will try.  You need to do a proper full installation into directories that do not have anything in them.

The JRE_HOME environment variable is not defined correctly
This environment variable is needed to run this program
C:\Program Files\sobel Jira\Atlassian sobel\JIRA\bin>

didn't understand 'Start clean with nothing in the new installation's home directory.'

Thanks

I suspect you've copied the original directory and hence inherited the lock files.

Start clean with nothing in the new installation's home directory.
