Setting up CRM to work with Outlook ?

Setting up CRM to work with Outlook ?

I've tried invane to setup the MS/Outlook plugin.
 
I've downloaded the plugin AdventNet_ZohoCRM_OutlookEdition
 
When I run it it does not install instead I get a message that tells me it will uninstal th plugin ?
 
So I let it uninstall it, but even that doesn't work ?
 
So I tried uninstall from control panel and that doesn't work either ?
 
Tearing my hair out here as I can't find any user guides on how to install, operate or unistall this plugin.
 
Can anyone shed any light on this ?
