separate 32bit and 64 bit versions?

Are there separate versions of the client software for this product, as im having issues with the mail shield functions on 64 bit windows 7 but its fine on 32bit xp and vista. Also has this product been tested with microsoft outlook 2010?

I have many installs of avast! and Outlook 2010. Is this IMAP?

yes it is. I have gathered now that it must be a software issue that avast know about as their updated 7.0.1451 version on antivirus pro seems to solve the issue. I Just hope they apply the same update to EPS plus.
