Installed 4.073 over 4.072 today. Did have to run the database tuner, as expected.
I would suggest that AC name the installation programs with the version number appended, Such as "amazing charts installer 4.073" instead of "amazing charts installer 4"
I got confused and downloaded the new 4.073 version but must have apparently ran on old 4.072 version on my hard drive as they had the same name.
Download to a shared folder took about 30 minutes, then it was another 30 minutes running in circles to all seven computers and installing.
