A Case of 'Abuse of Market Power?'
Microsoft Internet Explorer 4 Bombs Corel
Quattro Pro 7
A GOOD thing that Corel released a new version
of its Quattro Pro spreadsheet late last year because the
previous version -- Quattro Pro 7 -- can't be installed
on Windows 95 computers that already have Microsoft
Internet Explorer 4 installed.
Corel has confirmed to BugNet that the
presence of Internet Explorer 4 on a PC prevents
installing Quattro Pro 7.
Users who try to install Quattro Pro 7
get an Invalid Page Fault in Module Kernal32.dll
approximately 78 percent through Quattro's installation
Although the new Quattro Pro 8 isn't
affected, the problem remains a serious one since there
are tens of thousands of copies of Quattro Pro 7 in use,
and now virtually every Windows 95 machine ships with
Internet Explorer 4 (IE4) installed.
Users like Jann C. of Redmond, WA, are
finding that when they buy a new PC and try to install
their nearly new version of Quattro on it, they're in for
"Since I live in Redmond I suppose
I should be behind Microsoft 100 percent," Jann told
BugNet, "but what I experienced this weekend really
makes my blood boil! I bought a brand new Dell computer.
One of the programs that came preloaded on the computer
was Microsoft Internet Explorer 4.0. When I was trying to
install Corel's Quattro Pro (a direct competitor to MS
Excel, of course) it would only get about 78% of the way
through the install program and then it gave me an error
msg. I tried uninstalling and wasn't able to successfully
do that either. This caused me hours of frustration and
phone calls to Corel, Dell, Microsoft etc.
"Microsoft -- grrrr!"
The problem also has wider
implications. "If one accepts Microsoft's contention
that IE4 is a part of Windows 95, then you have to
conclude that Microsoft's operating system puts at least
one competitor -- Corel -- at a distinct
disadvantage," said BugNet Editor Bruce Brown.
"This can be seen as exactly the
sort of 'abuse of market power' that Microsoft's critics
are screaming about, in Congress and elsewhere."
The only work-around for the problem is
to uninstall Internet Explorer 4, according to Corel.
