If things aren't being uninstalled, it's typically because Windows Installer still thinks they're referenced.
Assuming you haven't marked the components as Permanent - in which case Windows Installer will never remove them - it's probably the legacy shared DLL reference count. Whatever you used to use to install these DLLs may well have left a count behind. In passing I'll note that the System32 folder is one of those locations that Windows Installer will initialise the shared DLL reference count, if not already present. Installing in private locations does not do this. You are strongly recommended not to install your own components in System32 unless absolutely required. If you want to share a component among multiple installers of your own, create a folder under [CommonFilesFolder], but note that both the definition/composition and GUID of the component MUST be identical in all installers. If you don't care about sharing the binary, place the DLL in your program folder. I would strongly advise against using regsvr32 /u. You should rely on Windows Installer to undo any registration when the components are uninstalled. The continuing presence of the registry entries is a symptom, not a cause. -- Mike Dimmick -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alexei Sent: 07 August 2007 10:28 To: wix-users@lists.sourceforge.net Subject: [WiX-users] DLLs and uninstalls Hey guys, I'm still struggling installing some DLLs...well - uninstalling some DLLs I've managed to get the fragments out of tallow, and to link my installer and it even seems to work. However when I uninstall the application the registry entries remain, and the files aren't removed from the WINDOWS\system32 directory. Am I doing something wrong or is this the way it's supposed to work? I've not really had much experience when it comes to setup development. I'm thinking of calling regsvr32 /u for each of the DLLs at the install and uninstall to make sure that the DLLs installed on the target machine are unregistered before the new ones are installed and that they are also unregistered upon uninstall. Therefore I'd make sure the registry entries are removed. Are there any drawbacks to this?
