Add-On Disabled

SP 2010+Outlook 2010

Installed "OK", then Outlook immediately made inactive. I've been able to find the following related error - Not loaded. A runtime error occurred during the loading of the Com Add-in

Does the file need to be installed from a specfic location on the local PC?

you don't need to install the program from a specific location but ,you should close Outlook before the installation.
If Add-in is disabled try this procedure to enable it:

In Outlook 2010 select file-> options
select Add-Ins on the left
select "Disabled Items" in Manage ListBox and click Go..
Enable Out2Share

I uninstalled the add-in and closed down OL. Reinstalled it. I can at least now get to my server. Yet, not all libraries. I have high enough permissions.

Sometimes connecting I receive the following error: startIndex cannot be larger than length of string. Parameter name:startIndex

3) Do you access root server or a specific subsite? (  or
