I am getting above error while trying to load octane. I am using unity 2018.3.3.
I have GTX 660 and latest driver version 430.86.
Both octane.dll and octaneunity.dll is present in the above file location.

Any idea how to fix this.

577 means that octane.dll has been corrupted.
126 means that octaneunity.dll is missing or cant be opened for other reasons.

Most likely something went wrong during the installation.

To fix it, go to your AppData local storage: "C:\Users\user\AppData\Local\Octane\Unity"
Delete all folders with 1371 in it.
Then start up your Unity project again, press load and re-download OctaneForUnity.

The following steps might help you fix the issue.

Octane plugins and OctaneRender are digitally signed, which ensures that the binary is legitimate and has not been corrupted or modified (I.e. it's safe to install and use).
This should not affect the installation or usage of our software, but there might be some issues in some cases, that should be easy to fix.

The error "Windows cannot verify the digital signature for this file..." (example below) can be caused by a number of factors, including:
win7SignError.png

The installer was corrupted during download (Try re-downloading the installer).
(Win 7 only): Your system has not been updated to support SHA-256 signatures, please follow the steps below to update your system:

1) Download and install the Windows 7 SP1 update utility from Microsoft here:

2) Download and install Security Update KB3033929 from Microsoft here:
https://www.microsoft.com/en-us/download/details.aspx?id=46148
The installer/application has been modified after download (This can be an indication of a virus on the machine)
Windows defender and/or other Anti-Virus programs may not recognize our certificate as 'trusted', so you may need to Install a certificate manually.

To check if our certificate is recognized by Windows, or to install it, you can right click on the installer file (eg: OctaneRender_for_3ds_Max_3.08-RC1_-_5.02.exe),
and open the tab 'Digital Signatures'. You should see "OTOY, Inc." as Name of signer.
Click on the Details button, (it should display 'This digital signature is OK.')
The 'View Certificate' allows you to install this certificate manually.
