You typically see this error when you had OMW installation (that version or older version) on that Windows server which had temporary 60 day license and that license has expired. The error is kind of safey check that forces OMW to not be installed without violating license! So verify if this the case.
When this error occurs and if you want to install OMW on that machine you have two choices -
* Rebuild the OS on that machine so it is a brand new server (of course if possible)
* You need a permanent OMW license that can be tied to the IP address of the server you are trying to install OMW on and then get in touch with HP Support. They can help you sort this issue without rebuilding the OS.
