Hi, I'm trying to get ECI VWAP working on SierraChart ARM64. However I got the error message in the log below. I've tried downloading prerelease and "Install Optional Components" however no success. The UserContributedStudies is not showing up under the "customs studies" either.

You need to update Sierra Chart to the latest release. That version includes ECI VWAP in the ARM64 version. You will find it in Analysis >> Studies >> Add Custom Study >> Sierra Chart Custom Studies and Examples. Sierra Chart Support - Engineering Level Your definitive source for support.

I've updated to v2858. The Usercontributedstudies worked once directly after the update. After a restart it stopped working again, getting the following result in the message log. 2026-01-11 13:27:54.981 | Found DLL: C:\Mac\Home\Documents\Windows\SierraChart2808\Data\UserContributedStudies.dll 2026-01-11 13:27:54.987 | UserContributedStudies.dll loading error.

The location of those particular VWAP studies is different: You will find them in Analysis >> Studies >> Add Custom Study >> Sierra Chart Custom Studies and Examples.

I understand the workaround for the ECIVWAP and got that working but how do I get other studies working which are included in the "UserContributedStudies" as it is not loading correctly.
