preparing the installation by execute the start.bat the wizard sends the message
"The wizard has detected an already existing SAP system NSP on this host.
But no SAP-System is installed. In Folder Software there is also no SAP-System to uninstall. The Folder SAP in Folder Install Shields has already been deleted before starting installation.
How can I find out what I have to delete too so that the installation is starting ?
1.Try Giving new SID,Central instance details.
2.Check in for services with old SID in services.msc.
3.go to run--->regedit
in HKEYLOCALMACHINE,look for Old SID.You have to manually delete those if they are present.
4.Go to Control panel---->settings.
Delete all old traces of Database,JDK.
5.Check in for users under "Users and groups" in "my computer-->properties".and also in program files.Delete,if there are any.
Restart the system once and retry.it will work.
