Can someone provide me with recent information that discusses the
installed base of the different versions of Microsoft Office for
Windows?  Specifically, I'd like to know what percent of Office users
use the following versions:

* Earlier versions
* Office 7.0/'95 (Word '95, etc.) - released August 30, 1995
* Office 8.0/'97 (Word '97, etc.) - released December 30, 1996
* Office 9.0/2000 (Word 2000, etc.) - released January 27, 1999 
* Office 10.0/2002/XP (Word 2002, etc.) - released May 31, 2001 
* Office 11.0/2003 (Word 2003, etc.) - released November 17, 2003

I can't find anyone who has collected numbers more recent then those
cited in the fontstuff.com Web site. However, I may still be able to
help you.

I can develop equations measuring the changes in relative market share
over time, then extrapolate the available numbers to estimate current
market share. Would that be acceptable as an answer?

Thanks - I had seen that.  I was hoping to find something a little
more recent, as their data was about a year old...

Hi Josh,

After further research, I was only able to locate the following
information from an article dated November 4, 2004.

"...But the greatest competition to the current Microsoft Office 2003
are older versions of Office still in use in many enterprises, Silver
said.

For example, he pointed to an ad hoc survey taken at a recent Gartner
conference, where about 15 percent of enterprise customers reported
using Office 97, even though the software has been orphaned by
Microsoft and suffers from a growing list of security issues.

"To Microsoft's dismay, Office 97 didn't stop working when they
stopped supporting it," Silver said. "Since Office 2000, companies
have moved very slowly to upgrade, although Office 2003 has an appeal
for mobile workers."

According to Silver, about 45 percent of larger enterprises are still
using Office 2000, with less than 10 percent using the current Office
2003. He expects a greater shift to Office 2003 in 2005."

The info I found doesn't go back that far, but I did find this from
October 10, 2004:

According to technology think tank Gartner Inc., Office 2003 was
projected to capture just 1 percent of the market a this year.
Three-year-old Office XP remains the leader with 50 percent market
share, followed by Office 2000 with 45 percent. Even Office 97, which
saw its technical support cut off by Microsoft in January, was
expected to retain a 4 percent market share.

I would be that there is negligible market share (well under 1%) for
all older versions.
