It sounds like you want to MS Access run-time distribution, which you can find here:
This (as it says) "enables you to distribute Access 2010 applications to users who do not have the full version of Access 2010 installed on their computers."
In other words, its the bits that your application needs if a full version of Access is not present.
There are installers there for 32 and 64 bit versions. You can just bundle that installer into your own.
As far as licensing and conditions go, it says: "You do not need to buy any special product in order to redistribute the Access 2010 Runtime. You can freely redistribute it or point users to this download."
So in other words - redistribute it as you like.
If you don't want Access 2010 runtime, there are available from MS runtimes for other versions of Access as well.
