Whenever I am trying to start elasticserach from windows command prompt. I am getting following error.
Error: Could not find or load main class Warning:
I installed elasticsearch from .MSI installation file.

I had the same issue, forget about MSI it is still in beta, download the zip file and execute the bat.
[https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.5.1-windows-x86\_64.zip](https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.5.1-windows-x86_64.zip)
unzip and execute:
bin\elasticsearch.bat
Works for me!
