I am desperate for help - hoping someone out there can get me through this.
I am new to InstallShield. I have the .ism files from our previous employee to work off of. He was on InstallShield 12 - I am upgraded to 2009.
When I run his original full install (using v12), then run my patch (using 2009), I can uninstall without a problem.
When I run my product install - I can uninstall without a problem.
If I run my full install, then install the patch over it, I can no longer uninstall. The install attempts to run as a new install rather than maintenance, and then tells me the GUID already exists in the registry.
Welcome to the forums Annetteqa. Unfortunately I do not have a quick answer for you only a few more questions.
1. What type of setup is this? Is it a Basic MSI, InstallScript MSI, or pure Installscript installation? 2. If it is a Basic MSI have you tried enabling logging - if so do you mind posting alog file for us to examine? To enable logging in the registry: [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer] "Logging"="voicewarmup" 3. Does the method of uninstall make a difference here? For example if you uninstall using Setup.exe is the behavior any different from Add/Remove programs?
My guess is that you have a pure InstallScript install and that something is causing it to choose the wrong install path in this one scenario. However, that is only a guess.
Not sure what happened - although I did clean out my registry when I couldn't uninstall so maybe that cleaned something out correctly - but my results have changed somewhat.
I am using an InstallScript MSI.
When I try to uinstall using the setup.exe the application uninstalls as it should.
When I try to uninstall from Add/Remove programs the patch install attempts to re-run.
