64 bit vs 32 bit ACT

[equest]

I should have remembered this, but how do I determine if I installed Act as 32 bit or 64 bit?

Also, what is the procedure for migrating from 64 bit to 32 bit on ACT?

[Roy_Laudenslager]

ACT! is only 32 bit. It works on 64 bit systems and with 64 bit office.

thanks Roy.

Do you know if it works better with Outlook 32 bit or Outlook 64 bit?

[Roy_Laudenslager]

32 bit Outlook with any version of ACT! 18 or below.

thanks.

i'm on Act! Pro Version 19.1.63.0, Update 2, does that matter in your opinion?

[Roy_Laudenslager]

That should be good for 64 bit Outlook.

I disagree, I had to go back to 32bit Office with Act v19 as 64bit Office continuously gave me errors especially when doing a mail merge

Sitt1965,

I completely agree with you. While on Office 2013 64 bit, I performed all the same "fix" procedures you did and a bunch more (including hours on the phone with tech support); all without success.  99% of my issues arise with Outlook.

Then I uninstalled Office 64 bit and installed 32 bit and resolved most of my problems. I'm still experiencing some so I now have to uninstall both Office and Act and do brand new installs of both (my mistake was not also uninstalling ACT).

Anyone out there considering installing Office 64 bit, I would highly recommend against it. Act does not work with Office 64 bit. I don't understand why Act just doesn't tell its new customers that it doesn't work with Office 64 bit.
