ER Plus v4.6 Build 4610: MS Outlook Error

ER Plus v4.6 Build 4610: MS Outlook Error

ER Plus is installed on a Windows 7, 64-bit machine that already had Outlook 2007 installed. I got the error about Outlook when I tried to run Mailbox Size reports. So, I removed Outlook, including any updates for Outlook. I rebooted the machine, but I'm still getting the error stating that Outlook is installed. Please advise. I'll re-install ER Plus if I have to but, if I would prefer to fix the issue without a re-install. Thanks.
