How to delete Dialog instance on NW04

Question

Hi guys
I have an installation NW04 on Cluster MSCS:
Central Instance on node A
SCS instance on Cluster Disk
Dialog instance on node B
We have performed upgrade to NW04s, and now in postprocessin we should deinstall Dialog Instance and install it again with software NW04s.
Here documentation guide:
****************************************+
After the upgrade of the central instance, you need to upgrade the dialog instance to the new release.
Due to the fact that some special settings and binaries on a dialog instance cannot be upgraded
remotely, you can only upgrade a dialog instance by uninstalling the old instance and then installing
a new dialog instance with the tool SAPinst.
Procedure
1. Uninstall the old dialog instances as described in the document Installation Guide ‒ SAP Web Application
Server 6.40 Java on <Operating System>: <Database>, Part II Installation and Post-Installation.
2. Install the new dialog instances as described in the document Installation Guide ‒ <SAP NetWeaver /
SAP application> <Technology> on <Operating System>: <Database>.
Point 1, is :
*************+
1. Log on as a user with domain administration rights.
2. Choose Start u2192 Settings u2192 Control Panel u2192 Add/Remove Programs.
3. The Add/Remove Programs dialog box appears.
4. Find the SAP entries.
. Note
Each SAP instance that is installed on the computer is listed with an entry like SAP Application Server
for System <SAPSID> instance.
5. Choose Remove.
The SAP Uninstall Wizard starts.
6. In the Welcome window, choose Next.
The dialog box Uninstalling SAP System appears for you to select an uninstall method
Depending on your selection, note the following when you use the check box to delete an SAP instance:
-- If your check box is marked gray, you delete or uninstall the following:
The SAP instance directory, for example:
\usr\sap\<SAPSID>\D00
Services, for example:
SAP<SAPSID>_00
The whole system directory, for example:
\usr\sap\<SAPSID>\*
-- If your check box is marked black, you delete or uninstall the following:
The SAP instance directory, for example:
\usr\sap\<SAPSID>\D00
Services, for example, SAP <SAPSID>_00
The whole system directory, for example:
\usr\sap\<SAPSID>\*
Local and domain user accounts
If you have different SAP instances that use the same <SAPSID>, you can delete the instance
directory only.
The wizard informs you when the SAP system or selected instances have been deleted successfully
But in my node B there is no SAP entry on Start u2192 Settings u2192 Control Panel u2192 Add/Remove Programs, however Dialog Instance exists, and windows service exists...and so on...
So how can we deinstall this dialog instance???
Thanks and regards

Hi
In node A there is JC30 (Java central instance)
In node B there is J32 (Java Dialog instance)
SCS31 (Services Central Instance) is now in node A, but can be switched.
Database Instance is OUTSIDE, is located on a Unix Server. (is not affected in this case)
Looking node B, there is no entry on Adding/Removing Programs regarding to SAP instance.
Of course, I can see windows services on node B, one for J32, other for SAPoscol, and one more for SCS31.
Any idea?
Thanks
Javier
