ACS tools package gives error in AEM 6.4.8

[Varun7990]

I am using AEM 6.4.8 and acs-aem-tools-content-1.0.2 for using the /etc/acs-tools/vlt-rcp.html feature.

First the bundle was not active and it was giving error "Missing Netty dependency" , Then I deployed com.adobe.acs.bundles.netty-1.0.2.zip package .

It solves the dependency issue and bundle is active but still I see the issue using the feature

VLT-RCP endpoint could not be reached.
Download and install VLT-RCP on this AEM instance.
Ensure the Apache Jackrabbit FileVault RCP Server Bundle is Active.
The VLT-RCP endpoint URL must be accessible and not blocked via Dispatcher or another reverse proxy. Note: The VLT RCP servlet endpoint changed from "/system/jackrabbit/filevault/rcp" to "/libs/granite/packaging/rcp" in VLT-RCP 3.1.6.

So what about

Download and install VLT-RCP on this AEM instance.
Ensure the Apache Jackrabbit FileVault RCP Server Bundle is Active.

Which version of this bundle is running in your instance?
