R82 SmartConsole (1063) won't start - "Could not load file or assembly..."

[George_Ellis]

I just started a Diamond case, but...
I have some folks getting this error message trying to start the SmartConsole thick app (R82, Build 1063).

Could not load file or assembly
'CP.Management.Objects.Schema.ManagementBl
ade, Version=0.0.0.0, Culture=neutral,
PublicKeyToken=null' or one of its dependencies.
Operation is not supported. (Exception from
HRESULT: Ox80131515)

Has anyone encountered and solved this one?

TIA

Edit - Grok AI says this is probably a Win 11 issue and suggests this command via power-shell

Get-ChildItem -Path "C:\Program Files (x86)\CheckPoint\SmartConsole\R82" -Recurse | Unblock-File

Waiting for one of the folks with the issue to respond.

I see chatgpt also points to that command as recommended method.

Best part is we now have it here in CheckMates.  So if someone has a similar issue, Search at Support should get a hit.

Sounds like a local issue. To be sure make sure your account works on other system that have console installed. 

You can try to reinstall SmartConsole. Or clearup some cache:

To resolve the problem, rebuild the local client cache:
Rename the local client cache folder:
For R81 and R81.10 Version:
'%localappdata%\Check Point\R81\SmartConsole\UserSettings' to
'%localappdata%\Check Point\R81\SmartConsole\UserSettings.old'.

For R81.20 Version:
C:\Users\user_name\AppData\Roaming\Check Point\R81.20\SmartConsole\UserSettings to
C:\Users\user_name\AppData\Roaming\Check Point\R81.20\SmartConsole\UserSettings.old
Note - This clears cached settings in the client such as username, server IP address, certificate trust etc.
Relaunch SmartConsole and log into the affected domain server.

It was Windows 11 (2H25) blocking execution as the files were marked as untrusted/blocked during installation.  A reinstall or a change in the permissions fixes it.  It is not cached credentials.
