Unable to compile custom assembly. Original version has been restored.

[Bidder]

Hi, Brand new install of NT8. Upon first reboot after install the message (Unable to compile custom assembly. Original version has been restored. You need to recompile your custom NinjaScript files.) Appears.

This is a brand new install and NOTHING has been loaded or modified after installation.

I can't see the entire error message nor can I see all of the compile erros, but I suspect that there may be duplicate files in your references. Was NinjaTrader installed previously on this PC? Or was this the first installation ever? Do you have multiple drives on this PC? Or is there only once (usually the 'C' drive)?

Could you provide a screenshot which shows all of the compile errors (vertically expanded) and then expand the error column slightly horizontally to see if there is additional size to the error message itself? I've highlighted the two areas which need your attention:

Same error happening on two different pc's. It's a new install on both machines. There is a c: and d: drive and all defaults on the install were taken. See graphic attached

Nevermind. I found it.

The root issue here is that there were other processes running on my system making changes to the files in the default NT location (C:\Users\Administrator\Documents\NinjaTrader 8). Two ways to solve the issue. 1. I can make changes to the way my system works and stop it from making changes to the location referenced above. 2. Create a symbolic link and move the NT files. See (https://ninjatrader.com/support/foru...orage-location).

Also NT could provide a native way to specify the location of its config files. This is a feature found in many if not most tier 1 applications.

Hello I am receiving the same message. Not sure how to fix

"Unable to compile custom assembly. Original version has been restored. You need to recompile your custom NinjaScript files."
Could you help please?

Hello jeanpaultru,

Thank you for your post!

Let's try testing your platform in Safe Mode to automatically trigger a recompile of your NinjaScript files.

Safe Mode will prevent NinjaTrader from:

• Loading workspaces and connecting on start-up.
• Loading custom assemblies (i.e. 3rd-party add-ons and NinjaScripts)
• Getting instrument updates from the server

To enable Safe Mode, please use the following steps:

• Shut down NinjaTrader.
• Hold the CTRL key and double-click the NinjaTrader icon.
• Keep holding the CTRL key until you see the Control Center.
• You may then verify you are in Safe Mode by going to Help -> About.

Once you have successfully opened the platform in Safe Mode, please close the platform and attempt to reopen normally. Does the error persist?


If it does not return, it indicates the error was isolated only to your other Workspace. I also suggest making a backup of your workspace so we can restore a working version of it if the issue returns. You will want to keep this backup file on an external hard drive or uploaded to a cloud drive such as Google Drive, Dropbox, or OneDrive.

To create a backup, go to the Control Center > Tools > Export > Backup File. Additional information about backups may be read in our Help Guide linked below.

• NinjaTrader 8 Help Guide — Backup and Restore

Please let me know the results of this test. I look forward to your response.

My Ninjatrader will not open once it starts loading it will show this prompt and after it will show this one before quiting



What do you recommend?

Hello jeanpaultru,

I'd be happy to help you with this, but do need a bit more information before I can determine a resolution. I'd like to review your log and trace files. Since these contain personal data, I'd prefer that we continue working on this issue via email.

Please email us at platformsupport [AT] ninjatrader [DOT] com. In your message, please include a link to this forum thread and a message 'ATTN Kennedy'.

Additionally, please follow the steps below to manually attach your log and trace files to your email so I may investigate further:

• Open your NinjaTrader folder under My Documents.
• Right click on the 'log' and 'trace' folders and select Send To> Compressed (zipped) Folder.
• Send the 2 compressed folders as attachments to this email.
• Once complete, you can delete these compressed folders.

Thank you in advance, I look forward to assisting further!

Good morning,

I was having this issue on my NT. Installed last version, and repaired it later again with the ninjatrader installer.



I started the safe mode, but when trying to open the Strategy builder I get this error:



I then open Ninjascript editor, press F5 to compile, and get this errors:



Also, from other threads I tried deleting the 'Documents\NinjaTrader 8\bin\Custom\obj' folder but it just do not show on my windows that obj folder inside the Custom path:



Can I please get some advise on how to solve this?

To simply add, I just pasted a code into Ninjascript and compiled it, and then all this started to happen.

Thanks in advance

Hello!

This error is caused when NinjaTrader is searching for a reference to a .dll file, and the reference does not exist. Steps to Resolve

1. Right-click within the NinjaScript Editor window and select "References".
2. Click "Add".
3. Locate the .dll file for the file mentioned in the error.
4. Click "Open" to add the reference.
5. Click "OK" and recompile.

Video Example of Resolution: Repeat these steps for each indicator listed, and once all of the errors disappear, you will be able to import, remove, and edit your add-ons normally.
