Elastic-search 7.7 service not getting started

Question

Installing Elastic-search 7.7 service not getting started we are are getting following error

Error "the system property [es.path.conf] must be set" when starting the service registered

Answer 1

After Investigating the elastic search logs (path: c:\elasticsearch-7.7.0\logs\elasticsearch-service-x64-stderr.YYYY-MM-dd)

Error "the system property [es.path.conf] must be set" when starting the service registered

Refer to the link for the fix

Solution:

The fix provided here [#57769][2] doesn't help since the culprit is not the same variable, I had to add the line
if not "%OTHER_JAVA_OPTS%" == "" set OTHER_JAVA_OPTS=%OTHER_JAVA_OPTS:;;=;%
before calling "%EXECUTABLE%" (after line 205) to file elasticsearch-service.bat

Hope this will help if anyone face a similar issue.
