Managed Package Installation Issue (You can’t specify version for namespace sf_com_apps because this namespace is not installed to your organization)

 Hi,

When we face the following issue while installing  any package then install the "sf_com_apps".

Problem:1. You can’t specify version for namespace sf_com_apps because this namespace is not installed to your organization.
: You can’t specify version for namespace sf_com_apps because this namespace is not installed to your organization.

You can install "sf_com_apps" in two way mainly.

1. Login to workbench from your Salesforce instance then Salesforce installs "sf_com_apps" automatically in few mins
2. Install the package using the following package URL: https://login.salesforce.com/packaging/installPackage.apexp?p0=04t30000001DUvr
