Trying to install Sketchup on Windows 7 (64bit) and during the install process I get a generic error: “An internal error occurred” and the install quits prematurely. This happens on all versions: Pro, Make, 2014 and 2013 versions. How can I diagnose this? Anyone ever run into this? I had sketchup 2013 (with many hours of trial time left) installed and it worked fine, but unfortunately I uninstalled it hoping it would get rid of the error.
Turn off your Anti-Virus during the install.
Make sure you have Administrative Rights (or run the installer with elevated privileges.)
