Mini SAP 6.1

Hi. I tried to install mini SAP but got the message:

Error: SAPDBINSTALL_IND_ADA ExecuteCheck 2 1195

Exit code from E:\sapdb\NT\I386\sdbinst.exe: 1.

Error: SAPDBINSTALL_IND_ADA InternalInstallationDo 2 1195

Phase failed.

Error: SAPDBINSTALL_IND_ADA InstallationDo 2 1195

Phase failed.

Error: Main {} 2 1195

Installation aborted.

What is wrong?

Thanks,

Itay
