Cause

The Microsoft component msxml3.dll is either missing or not correctly registered on the Windows agent machine, preventing the agent from parsing task metadata.

Resolution

Follow these steps:

1. Shutdown Client Automation 

2. Backup the current registry and then run Command Prompt as Administrator and then run

regsvr32 C:\WINDOWS\system32\msxml3.dll

regsvr32 C:\Windows\SysWOW64\msxml3.dll

Make sure for each command there is a message confirming the registration is good. If not, please work with system administrator or contact Broadcom Support.

3. Start Client Automation

If after these steps the issue persists, please contact Broadcom Support.
