fix: improper error handling when OpenAEV agent installation is blocked by EDR

[sairam-jetty-filigran]

Description
When attempting to install the OpenAEV agent on an endpoint protected by an EDR solution, the agent installer binary (agent-installer-session-user.exe) is blocked from executing. The EDR flags/prevents the binary from running, resulting in an "Access is denied" error. This is expected behaviour from the EDR's perspective (blocking unknown/unsigned binaries), but there is no guidance or workaround documented for deploying the agent in EDR-protected environments.

Expected Output

The agent installer binary should execute successfully, or throw proper error to be able to understand the issue and troubleshoot accordingly.

Actual Output

powershell
Copy
Note: PowerShell 7 or higher is recommended. If the issue persists, consider upgrading.

Impact: Prevents agent deployment entirely in EDR-protected environments without manual intervention (whitelisting).

Suggested improvements:

Provide official documentation on required EDR exclusions/whitelists for the agent binary
Error handle to show more approriate error message to be assist troubleshooting
