Two readers report older versions of cross-platform software not running in Snow Leopard. Ausilia Corso said that Office 2004 no longers runs after upgrading to Snow Leopard:

I just installed Snow Leopard and now can't open Mac Office 2004 not for love or money. Have gone looking for a fix, both from Microsoft and Mac and no one seems to have one. I have uninstalled and installed Mac Office 2004 to no avail. I'm trying to run a business and frustrated.

William Jackson reports that an older version of CrossOver no longer runs after installing Snow Leopard:

Crossover 7.1 won't run under Snow Leopard. Bounces tries to open, but doesn't. The current version of VMware 2.0.5 runs on Snow Leopard with a Windows XP VM. It connected to the Internet without a hitch.

The current version of Crossover, v8.0, does run in Snow Leopard. CrossOver runs certain Windows programs on Mac OS X without the use of Windows.

On Monday, we reported that Snow Leopard does not run older versions of Parallels Desktop, though it does run the current version without problems.

Chris Carrier believes that a previous report about Office 2004 not working in Snow Leopard may be because Rosetta isn't installed:

I have not had any problems running Office 2004 after installing Snow Leopard. You just need to manually install Rosetta from the Snow Leopard install disk. It did not automatically install in my case. From memory there is a folder called something like "Other Installations" or something similar on the Snow Leopard installation dialogue box. Click the "package" inside it and select the Rosetta option from the list, then all should be well. Might want to reboot after just to be sure.

Phil Ershler has another suggestion

I'm having no problems whatsoever with 10.6 and MS Office 2004. My only suggestion is to make sure that the version of Office 2004 you are trying to run has all of the current patches applied.

Robbie Thielemans responded to a report about problems connecting to Exchange Server from Snow Leopard Mail:

I have same issues here from the moment I upgraded to Snow Leopard. Whilst connecting to Exchange with Entourage, it constantly loses connection (error, cannot connect to server). Sometimes I need to retry ten times to send the same email. All the settings have remained the same as Leopard. I have no idea what causes this, and professionally this is really not workable.
