Hello and welcome to the forum.
I am sorry to hear about the problems you are running into. But, without any details at all, we would only be guessing wildly.
Now, installing any software requires a certain amount of knowledge and following the installation guidelines given by the manufacturer(s).
For us to help, we would need to know:
-- what DAW are you using?
-- or do you want to use the standalone SampleTank program?
-- what have you done so far?
-- what problem(s) did you run into?
As this is primarily a user to user forum, someone-else may chime in. Meanwhile, the best thing to do is raise a Support Ticket, here:
http://www.ikmultimedia.com/contact-support/mi/for some one to one help (US (East Coast) Business hours, generally). But, they will need details too.
