CE 7.1 Update from SP04 to SP07

26 Views

Hi,

We need to update CE7.1 system from SP04 to SP07 on Windows system.

When we run CEUPDATE71_0-10005101.exe which come along with downloaded stack, we get following pop-up.

Unable to find any Java instances on the host. Installation will terminate now.

But when we click on Ok button which is only available button on that pop-up, it wont go and again appears.

Only thing to terminate it is to kill that through task-manager.

Now regarding the Pop-up message "Unable to find any Java instances on the host. Installation will terminate now.", Java instance is up and running on host , also when we check sapint_dev log, it is also says "found instance". End portion of sapinst_dev logs is as follows.

So please suggest hos to proceed here.

When we open JSPM, it is able to run and detect SP07 stack. But as per CE 7.1 update guide we need to use this CEUPDATE7.1_******.exe (which comes along with SP-stack) to update CE system.

waiting for reply.
