Hello Pala,
Just to eliminate the doubt i downloaded 8.1.2.59 of XMC with new eval license.
i am still getting the same response which is, the netsight Database will load without any issue, after then via services manager if i try to start the Netsight server.. it will never get started and will give no warning or error.
Is there any step in installation that i have skipped but again i did installation 2 times, it didn't ask for anything which can have impact on server or database setting, or is it Windows 10 an issue here?
