Some customers have trouble installing our web based EXEs

[pfennig]

Our web based exes don't include the help files (*.chm and *.pdf), but give the opportunity to download them during installation or just skip them.
About 5 % of our customers cannot complete the installation process.
This seems to show two different symptoms, varying from customer to
customer:
1. the download stops at a certain percentage, usually the same at each
try for the same customer,
2. the customer gets the message that the installation "can't copy
files to the local folder".

Our installation requires admin priviledges. We verify them at the very beginning of the installation, so that shouldn't be the reason.

As Application runtimes we use Microsoft Windows Installer 2.0.

While it usually works for all in the company we could reproduce this behavior when we weren't quick enough to tell our firewall to allow the connection.

Ideas for a possible solution will be very much appreciated.
Our current one is an alternative download that includes the help files
but they're very comprehensive. Therefore, this is meant to be a
temporary solution only.

Is there an option to generate a log file during setup that helps to
bring light into this story?

Best regards

Make sure that there is enough free space on the TEMP directory specified on each one of the Windows.

It sounds more like an space issue at me.
