Question
Why cannot I perform any change in BVMS Configuration Client and why does the Operator Client keep restarting?
Answer
For example, if you want to perform a change of a camera in BVMS Configuration Client, such as removing or saving new presets, if preset cannot be removed or saved in BVMS and the Operator Client keeps restarting, the root cause is often related to insufficient user permissions on the workstation.
Typical symptoms include:
Presets appear to be removed in BVMS Configuration Client, but the changes are not saved.
After clicking Save and Save & Activate, BVMS CC repeatedly restarts.
An unexpected error appears when trying to log in to BVMS Configuration Client.
Only the Operator Client on the workstation restarts repeatedly (Configuration Client is not affected).
If you read the logs, they will show multiple restarts of: OperatorClient.exe
Windows logs show Group Policy–related warnings such as:
“0x80070005 Access is denied”
and
Group Policy preference item did not apply due to insufficient rights.
This restart loop can occur after any configuration change, not only when removing presets.
If the Configuration Client attempts to activate a change but the Operator Client cannot update the necessary files due to restricted permissions, the restart loop begins.
What causes this?
The error 0x80070005 Access is denied indicates that the current Windows user does not have the required permissions to modify registry entries or configuration files.
When BVMS activates configuration changes, the Operator Client must write and update specific files. If the user account is restricted by Group Policy, these updates fail. As a result, the Operator Client cannot properly store or load the updated configuration and enters a restart loop.
This access restriction can also prevent preset changes from being saved.
To double check and confirm that the issue is caused by insufficient permissions:
Run the Operator Client using Run as Administrator.
If the restarting stops, the issue is confirmed to be permission related.
What is the solution?
You will need help from someone who has the necessary rights on the system, who can:
Adjust the user permissions on the workstation.
Update or unblock Group Policies that restrict registry access.
Ensure the BVMS client has full permission to write to its configuration directories.
Only after sufficient rights are granted, BVMS will be able to save configuration changes such as removing presets, and the Operator Client will stop restarting.
