Outlook 2010 64bit v 32bit

JSlatem used Ask the Experts™
I have just upgraded from Office 2007 to 2010. My computer is 64bit BUT I have just discovered that two important pieces of software only run under 32bit and I installed Office 2010 as 64bit.
Does anybody see any potential problem in un-installing 2010 64bit and installing 32bit version so that the software works.
The software used in conjunction with Outlook 2010 is Spindle Professional 2009 and Act 2010 and the error message I am getting is "their is no default mail client. Outlook cannot run the message request" when starting up the system.
Many thanks.

Basically the advantage of using 64bit versions of software lies in the fact that it can use more RAM than the 32 bit versions. In the case of office you could notice that in very large excel worksheets or maybe with Access applications. If you haven't had any problems with your worksheets etc until now with office, then there should be no problem at all using the 32bit version.

This will be no problem, even the 32 bit version of outlook is recommende because if you install the 64 bit version your outlook add-ons and plugins must also be 64 bit. But most add-ons and plugins are only available in 32 bit so you cannot use them with 64 bit outlook
