As noted in a previous update post on my Foxit PDF Previewer for Outlook and Vista/Windows 7, there is an issue in the Office 2010 64-bit Beta (specifically Outlook) for executing 32-bit preview handlers on 64-bit Outlook.  I’ve got an update for those temporarily.

First, I can confirm that the issue is fixed in the later builds of Outlook 2010, so this fix is indeed only temporary.

Thanks to some assistance that Leo Davidson provided, I was able to provide a work around for my previewer that I’ve been able to confirm “works for me” on my installation of Outlook 64-bit on Windows 7 64-bit edition.

WARNING: This temporary fix involves messing with your registry.  You should do this with caution.  While I’ve done it successfully and tested fine, don’t hold me responsible if you computer catches on fire or neighbor pet animals die by doing this.  You should backup your registry before applying this to be safe.  Again, that said, it’s minor, only updates my application area settings and shouldn’t interfere with your settings.

The fix involves massaging some registry settings.  I’ve provided the registry settings in a file you can download here: FoxitPreviewerTempFix.zip.  There are two (2) registry files here.  Even though they are labeled 32-bit and 64-bit, they both need to be merged for this fix to work.  You should be able to double-click the .reg file and it will merge it auotomatically.  Additionally you can start regedit.exe and use the Import option (this is what I do).

Once complete, and assuming you have my previewer installed, then PDF preview attachment with my handler for Outlook 64-bit should be fixed for you.  Again, the requirement first here is that you have my Foxit PDF Previewer installed FIRST.

Please leave comments if this solved your issue.  This is ONLY for Outlook 2010 64-bit.  This is not necessary if you are running Outlook 2010 (32-bit), even if you are on Windows 64-bit.  That’s a lot of ‘bit’ talk I know.

Hope this helps! (and thanks Leo!)

Public service announcement – if you don’t use my Foxit PDF Previewer, please move along…there is nothing to see here :-).

When Windows 7 Beta came out (build 7000), there was indeed a confirmed issue where the Foxit PDF Previewer would not work at all on 64-bit versions.  There were no install warnings, it just wouldn’t work.  It turns out this was a Windows 7 beta bug for 64-bit (some COM registering stuff if you care to know).  This was found immediately and was fixed in later Windows 7 builds (I confirmed internally with the team and had been testing daily builds).

NOTE: This issue should have only affected 64-bit versions of Windows 7 beta.  32-bit versions were reporting unaffected.

If you will be testing out the Windows 7 Release Candidate for 64-bit, I can assure you that Foxit PDF Previewer will run fine on that build (I’m running it now).  If you choose to install the release candidate on top of the beta, you may run into issues where it thinks it still isn’t working.  I recommend if you are going to go this route, uninstall the PDF Previewer and then run the install again.  This will correct the registering of the software correctly.

I hope this helps!  The download link for the Foxit PDF Preview handler is the same as the Vista one located here.
