First time I've seen this in my years of using InstallShield starting with 6.3. We have a product installed using InstallShield 2011 and with one machine (2003 Server), when attempting to uninstall the product with the Add/Remove Programs applet it seems to run the installer normally rather than prompting to uninstall. I checked the registry key for the uninstall string and it's correct (with the GUID removed): "C:\Program Files\InstallShield Installation Information\{guid-removed}\setup.exe" -runfromtemp -l0x0409 -removeonly I checked that all the setup files do exist in the above folder. I tried running the above command directly via command-line but I get the same result. I even tried it with just the -removeonly flag and no change. It seems the -removeonly flag is ignored entirely and setup just thinks it's running for the first time rather than maintenance mode. Has anyone experienced this before and know of a solution? Thanks, Jon. ... View more

I use IS 2011 IDE on my workstation to develop/maintain our installations. We use the IS 2011 Standalone build on the build box to build our products and installers nightly. Both IsCmdBld.exe versions are 17.0.0.714. We are using the built-in Prerequisites dialog to check for and install dependencies as necessary, and they are setup to download from the internet. If I build the setup project using the IDE on my workstation, the prereqs dialog work as expected and only shows the selected prereqs to install if necessary or not at all when none are needed. However, the setups built from the stand-alone build on the build box show a different behavior. The prereqs dialog always show and --all-- prereqs are selected for installation regardless if the machine is 32-bit or 64-bit (it shows both in the list). When the "Install" button is clicked, the dialog just goes away then the installation continues. Please see the attached JPG image for what I mean. This is on a 32-bit XP machine that has all the prereqs installed but this dialog pops up no matter what. I've double-checked all the PRQ files on the build box vs. my workstation and they are all in sync. Is this a known issue with IS 2011 SAB that will be fixed soon or is there already a fix for it? I believe I installed the HotFix A version on the build box, but how do I verify that? Thanks, Jon. ... View more
