I am having an issue running the installer. I downloaded the ODAC 18c zip from Oracle. Unzipped to folder "C:\ODAC Installer". When I click on setup.exe, a window comes up briefly, then nothing happens.
I also tried running setup.exe from a command prompt, and had the same result.
Just documenting this in case someone runs into this frustrating error.
The issue was due to the space in the folder name for my install folder above. I used my phone to take a video of the window popping up, then went through the video frame by frame. I saw a reference to "C:\ODAC", which is not my install folder.
I renamed my folder to C:\ODACInstaller (no space), and the setup wizard starts up.
