Failed to Install the Agent on Windows

Scenario 1: User rdadmin Already Exists

Symptom

The Agent of application-consistent backup failed to be installed on a Windows server. Message "Agent working user rdadmin exist" is displayed.

Possible Causes

  • User rdadmin has been created on the Windows server before the Agent is installed.
  • If the Agent installation has been performed on the Windows server, user rdadmin will be created even if the installation fails.

Solution

  1. Log in to the Windows server, click the Windows icon in the lower left corner of the desktop, and choose Control Panel > User Accounts.
  2. Check whether user rdadmin exists. If the user exists, confirm that it is not created by other applications and then delete it.
  3. After the user is deleted, install the Agent again.

Scenario 2: Installation Failed Due to Registry Modification

Symptom

If you change the default encoding format by modifying the registry, the Agent may fail to be installed.

For example, you create an autorun entry under \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor and set it to chcp 65001.

Solution

Change the value to chcp 65001 > nul.

  1. Press Win+R to open the Run dialog box and then enter regedit.
  2. Go to the \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor directory.
  3. If autorun does not exist, right-click, choose New > String Value (REG_SZ), and name it autorun. If it exists, double-click to open it.
  4. Double-click and change the value to chcp 65001 > nul.
