SAP INSTGUI closes itself during installation of IDES ECC 6.0 EhP5

Hello experts,

i tried to install an IDES ECC 6.0 Ehp5 virtual, but during the installation (step: apab import) the installation GUI closes itself. ??? When i start the sapinst.exe a console window and the gui pops up, and the gui closes itself during apab import. The console window still remains till the installation is finished (i think that the installation is finished, but im not sure^^).

The VM works on and after some time (a couple of hours) the console window closes itself too. I now can start my SAP system and logon with SAPLogon. I entered SICK and the check is successful.

Is the sap system realy successful installed? How can i test and proof it?

Steps i did:

installed Windows Server 2008 R2 in a VM

-> done prerequisites like: pagefile, sap account, uac, firewall, hostname.....

installed MSSQL Server 2008 via vbs file

unziped jvm 4.1 from sap

started the installation and defined all parameters such as: jre, java_policy, crypto, kernel, inst. export...

entered hw key and started the installation

System:

Intel i5 2500k @ 4GHz

5GBRAM

350GB Disk

I hope that someone can help me. Thanks to all!

Best regards.
