Ok so it sounds like the need to run things in change user /mode to prep for
Citrix multiuser mode is not the be all and end all that I thought it was.
Up to now have always had an install program for all the apps so this
question never came up. But the counter suggestion here is that some install
programs can actually make things worse in some cases. Thanks

My in-house programmers create a slew of custom apps. They used to write
installers but I hated them. They didn't modify the registry, but they tried
to install files that I knew where already in the OS. I was sworn to that
if a DLL/OCX already existed they skipped to the next file (never
overwriting an existing file), but I personally felt that, in some
instances, they were overwriting files.
So, to deal with that, I had them write me a batch script that copied
DLL/OCX's to \system32 and registered them, say N to all overwrites. I run
that on my workstations and servers, and ANY custom app they write now
works. If they happen to get a new DLL/OCX they start coding with, they
tell me and I manually do it (rare that they add new controls to their
coding)
It works well doing it this, and I don't have to muck with installers that
don't always work, which meant I was frequently registering DLL/OCX's on
different machines to make new apps work.

It sounds like you are just making work for yourself, possibly without
bennefit. If the application install does not touch the registry, or the
logged in user's "application and settings" area (for example for making
shortcuts), then it makes no difference if you are in "install mode" or not.
A simple msi could just run a cmd script to do the install. This is all you
would need, although a second cmd script to do an uninstall would be nice.
Of course, even an MSI with just those two things will now cause a whole
bunch of stuff to be written to the registry when you install. Is it really
needed?

The vendor is lazy and thinks it is not required. They give our Apps group
the program files and they have been copying to workstations and just
running that way. Before letting this run on Citrix would like to take a
crack at creating an install for this
for the purpose of being able to install in change user /install mode so
things get a proper chance to be set up in the mutiuser environment that
Citrix\TS is. What things should I look for to know that the install program
will do what it ideally should for TS\Citrix? I have used an installer
program put out by Caphypon called Advanced Installer. Have run this and
created an .msi package that comes out to about 600 mbs - the program files
prior to being compressed into CAB files is at 1.2 Gbs. Seems to work but
not tested under load yet. According to the vendor there are up to 400
.exe's and many other supporting files and is reason program files so large
in size. This amazes me a bit as the architecture on the back end is MS SQL
so I do not see the need to be so fat on the client but maybe I just have
not been around long enough. Any thoughts would be appreciated.
