Do a FileSearch for the specific file, and based on that property condition your logo component to not install.

Subject: Re: [WiX-users] If file exists, don't update another file Hi Dave, I can't do that. Here is the explanation: we have a product which we release to different clients. We also have a partner with whom we bundle, so he wants to offer our product together with his, but the logo should stay his logo. We can't have his logo and our logo in the installer, as we don't want the clients digging that up. So we agreed on the following: first time when he installs the product he places a dummy file.txt into the installation directory and his own logo. When we provide an installer which is upgrading our software, in case the update is for our own clients, the logo should be updated, but if the upgrade is run by the partner-client the logo shouldn't be updated, so basically our update should check if the file.txt is there and if yes should not update the logo. In other words: if in the installation folder there is a specific file, eg file.txt, then a specific file, eg mylogo.jpg should _not_ be updated. And I'm not sure how one can do that when: <RemoveExistingProducts After="InstallInitialize"/> as from what I read, the product is completely removed first so his logo will be gone.
