This can be caused by outdated sidhistory agent files on the DCs used by DSA. -
Resolution
Stop all synchronizations and migration
Locate and delete (or rename) all of the below files from the DC giving the error:
%systemroot%\system32\AelAgentMS.exe (AelAgentMS64.exe on 64-bit DC)
%systemroot%\system32\AelAgentMS.cnt
%systemroot%\Aelita\AePAgent\PwdHlp.dll (PwdHlp64.dll on 64-bit DC)

Additional Information
This is caused by an open Services.msc snap-in (in any Windows Profile, active or inactive), which prevents our tool to complete the uninstall via MSI. A reboot of the DC allows the uninstall to complete.
