Installing the package from bank sales cloud instance 7.10.2 to On-site bank sales 7.10.2 instance

Hi, 

We have one bank sales cloud instance 7.10.2 and packages are stored in the SVN repository. We have access to export the package but we don't have access to the SVN server. We are trying to install the package from bank sales cloud instance 7.10.2 to On-site bank sales 7.10.2 instance. We have tried to install those packages using the "Installed Application" option also. But, we got so many errors. Please help us.

Thank you.
