I am having an issue with an installer which I created with the Application Builder. I have a project that I have successfully deployed. Subsequently I created another project (and vi) which is based on a copy of the originals, both with new file names. In the renamed project file, I changed all file names, paths, and all resources, to reflect the new names. I also changed the installer’s destination and install folders, of course. I reset the executable’s version number (in the Build Specification properties) to 1.0 (the original was 1.3). I then successfully built an executable and the application installer. However, when I run the installer (setup.exe), it gives a dialog (after the license screen) that it “Cannot install” because a “higher version already installed”. I’ve done exactly the same thing with other vi’s and projects of mine, and never had this issue. The installer correctly installs the newly created (and renamed) version where it is told to in the project file. Also, I’ve never had a problem deploying (installing) on my development PC either. I have carefully checked and rechecked to make sure there is no reference to the original executable or paths. What could be causing this behavior? I want to keep the two projects completely separate, so simply changing the version to higher than 1.3 is not an acceptable solution. Thanks to anyone in advance for any help and suggestions. Ed

Installer built with Application Builder gives error "Cannot install, higher version already installed"

Yes, I was thinking of just removing the 2 Build Specifications (the exe and the installer, probably only the latter necessary) from the project and re-creating them, but I decided to do the whole project from scratch to be sure (I was under a deadline and didn't want to experiment more than necessary). The next time (if there is a next time) I'll do what you suggest. Thanks.
