The NetSqlAzMan installer for version 22.214.171.124 (and 126.96.36.199) fails on Vista Ultimate (tried it on more than one PC).
A message is displayed stating that the file 'c:\Windows\system32\ObjectPickerHelper2.dll' has failed to register. The HRESULT returned is -2147010895 (0x800736B1). The user is offered a chance to retry the operation (it fails again) or
continue with the installation. Choosing to continue completes the installation but the product does not work correctly.
A workaround is to manually register the offending dynamic link library with regsvr32.exe after the installation completes.
The HRESULT value implies that the registration attempt might be occurring before a dependency of the named file has been installed.
