Installation of SAP NetWeaver 2004s ABAP from CD

[Former Member]

Hello,

by installing from CD I got the error message

"The wizard has detected an already existing SAP system NSP on this host.

Uninstall first".

How can I fix the problem and how and where can I uninstall this (not really existing) SAP-System ?

Thank You !

It seems that at one time or another you may have had a sneak preview version on your laptop. So there may be some registry stuff still hanging around. Download and run the registry clean tool from the download section here on SDN. Also make sure that there is no NSP or SAP folder under c:/ or a sapdb folder.
