Unable to install as a service

Good afternoon sir.

Recently,
I was download SCP trial for the purpose of test(renewal of SERVER(Hardware)),
and installed it on the test PC which has Windows7 Home Premium as OS.
(I was chose Professional version and postGREsql as a database)

But it showed as like the subject of this article,
'Unable to install as a service'
and couldn't start server and web client, either.
and, strangely, when I opened the Windows 'Service' managing tool,
it seems automatically started and worked well.
(C:\ManageEngine\SupportCenter\bin\wrapper.exe -s C:\ManageEngine\SupportCenter\bin\\..\server\default\conf\wrapper.conf)

I was installed to another PC, it was same like above.

Please help me.
There is no resolution of this problem on this forum, and FAQ.

Thanks.
