Far out, I have been suffering from the same issue! I have tried on multiple machines to install Lightroom CCP pacakge! When running the setup.exe for other packages it will actually install the application and display a desktop icon / program files entry. I have wasted hours trying to figure out why Lightroom wasn't installing even tho event logs said successful! How is there no official documentation from Adobe that this is the expected behaviour for Lightroom manual installs?
Sure the documentation says run setup.exe then exceptions installer, my thoughts were why bother with exception installer if the main package has not installed correctly! It should mention the program won't appear until exceptions have been installed?
Thanks for creating this thread DeltaCollege! And thanks for the resolution Romsinha!
