You may have a 64 bit version of Windows (Windows 7 x64) but this does not always indicate that you have a 64 bit version of Office 2010 installed. If you are not sure which version you installed, the following article will describe how you can determine the version you are using.

 Why use the 32 bit version of Office 2010 if I have a 64 bit operating system like Windows 7 x64?

The advantage of using the 32 bit version (the default installation, and recommended installation from Microsoft) is that your existing add-ons and templates that are designed specifically for 32 bit operating systems will (or should) continue to work with Office 2010. 

The advantage of using the 64 bit version of Office 2010 is that you can utilize more memory and handle larger documents within Office 2010.  So, unless you’re normally dealing and working with large files of 2GB or more, Office 2010 64 bit isn’t going to give you any advantage over the 32 bit version.

The following Microsoft Engineering Blog has some good information on this, http://blogs.technet.com/b/office2010/archive/2010/02/23/understanding-64-bit-office.aspx

NOTE: You can’t run mixed 32 bit Office and 64 bit Office 2010 components (side by side).  If you install Office 2010 64 bit, all your Office 2010 software will be 64 bit (Outlook 2010, Excel 2010, Word 2010 …)  The same is true for the 32 bit version.  If you have the 64 bit of Outlook 2010 installed, you must uninstall Outlook 2010 64 bit and install the 32 bit version to install any other Microsoft Office 2010 32 bit applications

If you’re using any of the following software products,  you’ll require the 32 bit version of Office 2010. 

• Sending fax merges with the FaxTalk Fax Merge requires a 32 bit version of Microsoft Word 2010. 
• WinFax PRO with a compatible operating system (Windows XP, 2003) will function with 32 bit Microsoft Office 2010.
• WinFax is not compatible with Outlook 2010 contacts.
• FaxTalk FaxCenter Pro 8, FaxTalk Multiline Server 8 and FaxTalk Messenger Pro 8 require the 32 bit version of Outlook 2010 to use contacts**

** FaxTalk FaxCenter Pro, FaxTalk Multiline Server and FaxTalk Messenger Pro can fax using 64 bit or 32 bit Office 2010 products.

How to determine the version of Microsoft Office 2010 installed

If you are not sure what version you have installed, you can check by clicking FILE from the Word ribbon, and then click HELP.

A 64 bit or 32 bit version will be indicated in the dialog box as shown. (32 bit or 64 bit will appear after the version information)

Repairing a log or phonebook database in WinFax can now be accomplished with ease using WinFax Tools.

Before rebuilding any data in WinFax please backup your entire DATA folder (or entire WinFax folder) where all your WinFax files are located.  We recommend this in case of any failure during the rebuild/repair process.  If you’re not sure where your WinFax files are located, WinFax Tools can determine the location of your DATA folder for you, click on WinFax Info.

1. Start WinFax Tools.
2. Click on Logs & Phonebooks button.
3. Click on Rebuild Log & Phonebooks button.
4. Click OK to the message “Do you want to rebuild log & phonebook files?”
5. If Outlook is currently running, you will be prompted to close Outlook. I recommend closing all other open applications except WinFax Tools.
6. You will now be presented with a dialog box asking you to select a specific WinFax database file with a ”.WFB” extension.  The default phonebook is called “MY-PH-BK” and the default send/receive/outbox log is called “STATUS”.  Select one of these files you want to repair, and click OK.  If you have additional phonebooks, they will be listed with the appropriate name.  Any additional logs (message stores) will also have their unique name.
7. Wait for the selected database to be optimized and rebuilt. Click CLOSE when done.
8. Repeat the steps for any additional databases you want to rebuild (if required.)
9. Click  Close in WinFax Tools.
10. Click Start Controller. The WinFax Controller should start and the database should be repaired.
