The following is the recommended procedure to upgrade from legacy Redirector to modern CPR:

1) Launch legacy Redirector and delete all IP host/TCP port mapping for every virtual com port created in Redirector. Save the settings so that the map is deleted.

2) Delete individual vcom ports created in legacy Redirector. Save the settings so that the vcom port is released from the registry.

3) Uninstall legacy Redirector from Control Panel -> Add/Remove Programs.

3) Reboot PC. This will completely remove vcom ports claimed by legacy Redirector in the registry.

4) After the reboot, install the most current CPR version and configure the new com ports as specified.  The current CPR is available here:

The important thing is to not uninstall legacy Redirector without first deleting the vcom port and IP host/TCP port mapping. Otherwise, the vcom ports will remain claimed in the registry and be inaccessible to any other application.

If the legacy Redirector was already uninstalled before vcom port and tcp host/port mappings were deleted, reinstall the Redirector and delete of all undesired mappings and vcom ports. Proceed with above procedure as normal.
