I have a situation where, due to a variety of attempts to get Adobe Reader up to date, some computers have 10.0.0, some 10.1.0, and some 10.1.1. Some were installed via wpkg, and others through Active Directory Group Policies. I now want to install 10.1.2 - but I want to turn off automatic updates. The management tool to customize it for this also turns off "uninstall previous versions", and the new version refuses to install if an older one is present. My question - can I create a package, or set of packages, to test for the presence of any of the older versions and run the appropriate msi to uninstall them? <check type=file condition=versionequalto ... > would seem to identify the offending version - how do I negate the action so it only uninstalls if successful, rather than the usual action of only installing if unsuccessful? I don't want to blindly try uninstalling, because that copies each msi in turn, and due to the 45MB size and the limitations of wireless networks, would cause far too much network traffic and disruption. -- Alan Adams, from Northamptonshire alan at adamshome.org.uk http://www.nckc.org.uk/ |
