Problems with Installation of SAP NW 2004s Trial Version from CD

[Former Member]

Hello,

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.

Uninstall first".

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 ?

Thanks

Hi,

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.

Helpful to me. Got a step further.

needed to delete local Windows-Service "SAPNSP_00" by command:

sc delete SAPNSP_00

I had this several times trying to get my AbapTrial version to work but then everything was successful as below:

i. windows command regedit ->software and delete the whole SAP folder

ii. at least disable the services (I had old SAP.. entries) (you did windows command sc delete)

iii. I had an NSP version and so deleted the whole of C:SAP folder and c:sapdb folder

iv. I went to windows software management and removed the trial version or went to Start->Programs and deleted the Trial version there.

v. In Start->Programs->MaxDB (or, once, in software management) I deleted all MaxDB entries.

As far as I remember everything was then removed.

The successful installation then was as follows:

I successfully downloaded from http://www.sdn.sap.com/irj/scn/nw-downloads and successfully ran the installation:

1) the download wasnt possible the first few times I tried - the download popup did not appear and I received a message with the word "scnsorry" instead. I just had to keep trying.

2) I downloaded the entry

"SAP NetWeaver 7.01 SR1 SP3 ABAP Developer Edition ".

Another entry, also offered for download, "SAP NetWeaver 7.01 - ABAP Trial Version " did not install and seemed to be in error. (Installed "successfully" in just 4 minutes and showed no MaxDB files in the unzipped folder).

3) I followed the instructions and the installation (some 27 steps) ran for 7 hours.

4) I am on a laptop with Windows Vista 6.0 Build 6002 SP2. (It is in German, not English, but this was not a problem, although it is sometimes mentioned that one should use an english-language OS).

5) After installation I could log on at once.

I recommend this way because it saves so much time.
