Security Manager 5.x

Security Manager 6.x


When clicking in the Control Center, you receive a constant error message saying the following:

An exception was received from the Central Computer

Exception details:
Return argument has an invalid type.


The problem here is that the remote console machine does not have the same hotfix and/or service pack level as the Central Computer. To validate this, you can perform the following steps:


  1. Go to Program Files\NetIQ Security Manager\Onepoint on the Central Computer and console machines
  2. Get properties on SMCommon.dll file on the Central Computer and remote console machines.
  3. Go to the Version tab and compare the version on both the remote console machine and Central Computer


If the version is different, then apply the correct hotfix and service pack level so that both of these numbers match and that should resolve the issue.


This is caused by the hotfix or service pack level being different than the one applied to the Central Computer.
