IndexFormatTooNew Exception in Elastic Search Installation (6.5.4)

I have downloaded Elasticsearch6.5.4 msi installer exe from Elastic Search Downloads page. I have installed Elastic search as shown in Installer Procedure in the website. When I am trying to run or start the elastic Search I am getting below error.

Exception in thread "main" org.elasticsearch.bootstrap.BootstrapException: org.apache.lucene.index.IndexFormatTooNewException: Format version is not supported (resource BufferedChecksumIndexInput(SimpleFSIndexInput(path="C:\ProgramData\Elastic\Elasticsearch\config\elasticsearch.keystore"))): 4 (needs to be between 1 and 3)

On MacOS (Big Sur) I had to remove Elastic search then remove the config files from another dir:

rm -rf /usr/local/var/lib/elasticsearch

After that, I could reinstall successfully.

I had the same issue. Removing Elasticsearch does not remove config files. In centOs I removed elastic search by

rpm -qa | grep "elasticsearch"
rpm -e --nodeps "output-of-above-command"

After that I removed elasticsearch folders from /etc and /usr/share

rm -rf /etc/elasticsearch
rm -rf /usr/share/elasticsearch

After that you can install the required version.
