Thanks you Billy, Rishi and Manas. One Issue was C drive going out of space. I did implement other solutions I found on net. I have all documented so when I reinstall I will confirm what was the real fix.
Now I am trying to generate Installation Key for ERP 6 IDES. I see on web to use SMSY but on my SolMan 7.1 SR1 I see Product System and technical System. I right click on both but can not enter a new system. It takes me to another screen to use Landscape Management DB. It opens a web browser which is not working in my case. So not sure how to generate installation keys for SAP ERP IDES.
