installation doesn't accept patch

[EP]

I have an installation (PackageA) that was originally distributed with a
single compressed setup.exe.

I've created a patch based on an uncompressed version of PackageA.

When I run Update.exe, I get this error:
"This installation cannot be run by directly launching the MSI package.
You must run setup.exe"

When I run the updated ism from that quickpatch, I get the following error
"Another version of this product is already installed. Installation of
this version cannot continue".


How can I patch this installation?

What update.exe is this? Patches are usually installed with a msiexec command
line like:
msiexec /p <your.msp> REINSTALL=ALL REINSTALLMODE=omus

It's an installshield developer 8 update.exe.

When I try the command line you provided I again get an error stating the
setup must be run from setup.exe.

Then you need to look at things like this - it's probably an InstallShield
issue.
