Install wizard ends prematurely

Trying to upgrade to the latest version but getting an error saying the install wizard has ended prematurely. Any easy way to fix this?

Sorry for the inconvenience. We need more details to analyze your problem.
Please run the installer with the argument /lvx [path to the log-file] .
Example: CESM_BE_Setup_2.0.50223.2.exe /lvx f:\temp\cesmlog.txt

Then send a private message with the log-file.

Thank you!
