The install steps ask for language : selected English (United States)
Then the QuickTime.msi unpacks
Next the ISScript11.msi unpacks
Status screen shows Quicktime 7.0.3.50 (latest standalone download
version available)
Steps to repro :
The licence agreement is shown and agreed to, then the install
directory (standard H:\Applications\Quicktime) is chosen. Then the
"removing applications" screen is shown as normal, followed by the
first error message "The installscript engine on this machine is
older than the version required to run this setup".
The application then shows the final screen, and pops up the (useless
to most users) error shown on image 2 - not a lot of help as there's
no reference to the MSDN page needed (and most users would have no
idea what MSDN meant !)
In my /program files/common/InstallSheild directory, I had a branch
for v7 drivers. Checking with this site
http://consumer.installshield.com/kb.asp?id=Q108158 suggested making
sure later versions were available too so I manually downloaded and
installed the ISScript11.msi package from Installsheild.
As you can see, that's already being installed as part of the QT
unpacking process - however the installsheild site suggests if the
installing program "version" is shown as "7" then v7 should be
sufficient. Why would the QT installer be set for v7 in the file
version, but unpack v11 during install, and why should it fail ?
I've also made sure to have the most updated "windows installer" 3.1
(v2) available, KB893803-v2, with no change to the outcome. To check
further, I tried the iTunes/QT composite package. iTunes installed
OK, but again QT failed when installing with an "error 3" something.
Clues / Suggestions ? Currently my test machines QT is "offline" due
to obscure error combinations !
