I am using a (custom written) setup bootstrapper with an embedded MSI
package, the bootstrapper extracts the MSI package to a temporary
directory, performs the installation and then deletes the temporary
directory. When later via Add/Remove Programs I try to add extra
features or sometimes during a repair the Windows Installer prompts for
the media with "The feature you are trying to use is on a network
resource that is unavailable". Unfortnuately as the MSI package is
embedded inside my setup bootstrapper I can't provide a valid path to
Windows Installer at this point.
One potential solution is to mark the package so that Add/Remove
Programs only offers a remove/uninstall option, but if possible I'd
prefer to keep the change/modify and repair options. In trying to
resolve this I have subsequently read that Windows Installer caches MSI
packages with any embedded files and cabinets stripped out.
1. Can the MSI package be marked in some way so that the complete MSI
file (under 5 MBs in my case) is cached by Windows Installer?
2. Can my setup bootstrapper call some MSI API to make Windows
Installer cache the complete package?
3. Should my setup bootstrapper copy the MSI package to a permanent
location on the local computer and perform the installation from
there?
If so can I prevent the Windows Installer doing it's own caching
since the MSI package will always be available on the local computer?
I would obviously prefer option 1 or 2 or any other similar option that
prevents my setup bootstrapper effectively maintaining an MSI cache of
its own. How do you setup bootstrappers, in general, avoid this issue?
Best regards,
Andrew
