How to remove old Flex Virtual Serial Ports (Fabulatec)

Hello OM:s
I have tried to remove previous Virtual COM ports from CAT SDR and they no longer are shown on the device manager. Even when looking at hidden ports. Howevere, when I try to re-configure COM ports to the FleX Ports I thought have removed they still turn up as in the COM port manager as in use. With another software (that remove COM Ports) I still see them listed.
Unfortunately I did remove the CAT SDR program from the control panel (remove programs) and not through the CAT SDR program uninstall procedures. 
Is there no way to once and for all remove all Flex Virtual COM Ports? 
I am in the process of re-installing SDR but I need to re-configure COM ports for other programs.

I would like to explain what is going on rather than allowing conjecture to continue which is muddying the waters.

First off, this situation where com port pairs reappear after being deleted is manifested by Windows and the not so graceful way it handles virtual com ports.  You have to do things in a particular sequence with the proper rights or Windows gets really confused.  Seriously confused.

The issues that are being described in this topic are a result of a few things.

1.) We provided a convenience feature where pre-1.6 CAT ports were converted to 1.6 type CAT ports.  In general this worked well, but it could result in a previous CAT com port pair not being converted depending on the initial state of your PC prior to the conversion.

2.) If you have a port pair that keeps showing up in Device Manager after you reboot and it is not a port pair defined in CAT, there is a way to re-associate to port in CAT so it can be properly removed.  This is not a trivial procedure, as it requires manual modification of a config file that is done improperly will make things worse. 

3.) FlexRadio Technical Support can fix this for you, but you must open a HelpDesk ticket so we can identify the port pairs, identify the un-associated port pair(s) and modify the configuration file to re-associate  the port pair(s) with the CAT Control Panel.
