I'm been using Sierra Chart on a Mac through Parallels for the last year with no issue. My Windows updated today and afterwards Sierra Chart wouldn't open. I looked in the Seirra Chart folder and saw Sierra Chart_Arm 64 as well as the original app (see screenshot). I opened the newer version, but when loading my chartbook, there were studies missing (see screenshot). I couldn't resolve this issue so lastly, I updated to the current version from the Help Menu to see if that would resolve the issue. However, when the installation was complete there were a number of error messages (see screenshot). I don't want to install again from scratch if I don't have to, but I don't know what else to do

Try download .zip file, extract it, and copy the highlighted files and 2 folders into your existing Sierra folder (see attachment). Actually this is always the way I am doing update, I never run installation file.

Thanks Tony, I followed your instructions but I'm still having the issue with the specific studies not showing on my charts. Sierra Chart_Arm 64 is running fine. I've tried opening other versions of this chartbook with the same studies, but they're still missing. These are custom studies that were made for me by a third party. There was no issue until this morning when I updated.

Here is the documentation for using the ZIP installer: Software Download: Sierra Chart Zip Installer Looks like you are missing some custom studies files. Go into the Sierra Chart Data Files Folder: General Settings Window: Data Files Folder (Global Settings >> General Settings >> Paths >> Files and Folder Paths) Do you see the DLL files there for them? Do you see the UserContributedStudies.dll file? Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I am getting the same thing when trying to do a new install using the installer on Windows Server 2022. First time it froze almost immediately, second time lots errors in the log and now on the third try, it's faster but still intermittent errors in the log. It's getting better, so maybe a connection issue with server that the installation files are on?

Yes, the installer froze on the first try after getting to "https://download3.sierra" from "https://download1.sierra" on the log. On the tries after, it was logging http errors; couldn't download certain files. No problems now, I just deleted and tried installing again and it was fast like normal with no errors.

When you say froze, was it in a frozen and inoperable state? We would recommend disabling security software and functionality: High CPU Usage \| Inactive User Interface \| Poor Performance \| Long Time to Load Chart Data \| Charts Reloading Often: 30.8 - Antivirus/Anti-Malware Software It does also sound like there was a connectivity issue as well.

I reinstalled the latest version of Sierra Chart as per the instructions, and I located the UserContributedStudies.dll file in the Data folder (see screenshot). It's the only DLL file in the Data folder. Unfortunately the two specific studies are still missing. Just to clarify, most of the custom studies on my chartbook are still there, it's just two that are missing Date Time Of Last Edit: 2025-11-16 17:11:40

I have had the exact same issues and still can not get the 64bit version to work but have managed to get the ARM version to work. I have lost all my settings in changing over to the ARM version. I took it to Apple thinking it was my 2023 Macbook Pro however they were not able to find any issues. The tech was very knowledgeable in parallels and not supposed to help in non Mac items but took nearly an hour to help in solving this problem. I wish I had seen this post prior to him erasing the previous version of Sierra Chart. I almost bought a new computer over this issue. Is there any advantage to running 64bit vs ARM? I have seen in previous posts where it was suggested to run the 64bit if possible. Any thoughts would be greatly appreciated.

Unfortunately the two specific studies are still missing. These studies must be in custom DLL study files that you do not have. You will need to obtain those from the custom study developer. Do you know who that is? Or did you develop these yourself? When there is an attempt to load the DLLs, and they do not load, you will see the names of them given in the Window >> Message Log. Check the log for the file names. This does not make sense: I have lost all my settings in changing over to the ARM version. Are you using the same installation of Sierra Chart? You just need to run the SierraChart_ARM64.exe file in the same installation folder. Settings cannot possibly be lost. This is not technically possible. This simply is not possible to happen. And there are backups of the global configuration that you can use: Resetting Sierra Chart to a Default State / Restoring Backup Global Configuration File: Restoring Backup Global Configuration File There are also backups of the Chartbooks and those are compatible with the ARM version. The ARM version is also 64-bit. You are probably asking about running the X64, versus the ARM version. We do not know the answer to that. We do not know Mac hardware and parallels well enough to answer this. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Originally I was trying to run the same installation and it wouldn't connect therefor none of the charts were loaded so I obviously made a poor assumption and thought it wouldn't run either. The apple tech I think tried reinstalling Sierra Chart which erased everything. I am lucky that I shared my chartbook with a friend over a year ago so not all is lost and I'm working through this now but it would be nice to understand why this stopped working in the first place as I prefer the look of X64 over the ARM version. In the end if the buy and sell button works I can figure out the rest. Similar to Seamus I was able to recover everything after the update once. Then it froze again as did I.

There is no difference in appearance between the two versions: I prefer the look of X64 over the ARM version. Unless the operating system, is creating a difference that we are not aware of. You mention "froze again". So are you running into a freezing problem in Sierra Chart? Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I think the operating system is the issue. The font has changed, it's bold and slightly larger. Like your grandfather borrowed your computer. At the moment I have not had any issues with freezing. It was only when the X64 version stopped working. It froze. One with a black screen no charts and the other was during futures symbol rollover on CL. It never finished the rollover and just crashed. It would not open after that but showed open in the CPU usage icon. The usage btw in task manager was frozen at 47% compared to the current fluctuations between 10-13%. If I forced closed Sierra Chart the cpu usage would drop to 0 and when reopened immediately freeze at 47%

The highlighted lines in the message log (attached) are the only mention of the DLL files. I want to restate that on Friday morning I opened my chartbook and everything was normal. I decided to update (through help menu) before I started trading, and since then these studies have been missing. The custom studies are from a third party. I downloaded them again from the source and replaced them in the Data folder, but the same issue persists. I will contact the chart creator and see if I can find a solution

Regarding post #14, that is definitely not normal. Are you running Sierra Chart on Windows? Regarding post #15, Regarding post #15, are you running the ARM version of Sierra Chart.

Yes I’m running the Arm version of Sierra Chart. The other one doesn’t open.

We wish we could give a good answer, and get these issues resolved, but the problem is these are just nonstandard set ups. In the case of issues with using custom studies, if we can get the source code for the custom studies assuming they are in the public domain and accessible to everyone, we can add them into Sierra Chart to make them easy to use in the ARM version. So try to get us to source code if it is in the public domain. Or if they are part of user contributed studies, we need to know the name of the study. We are getting a little confused because we are losing track of what are the current outstanding issues are and what issue each user is having.

I think I just need to rebuild these studies the best I can myself. I don't understand why only a few got corrupted and the rest were fine. I think I'll be quicker doing it myself. Thanks for your help.

Hi, I'm the original poster - I've found out today from someone using the same setup as myself (M1 Macbook, Parallels) that the Arm_64 version of Sierra - which is the only one that opens now - has difficulty opening the User Contributed Studies apparently. When chatting to this other user, he asked me why I was using the Arm_64 version as he had experienced this issue. Is there any way I can use an older version of Sierra Chart and go back to the way it was last week?

On the installer, in the dropped down menu for Version you can choose "Specific Version" and then put in the version number in the box to the right. You can check the Sierra Version Notes, to see which version you want.
