Monday mooning eh? It surely is!
Trying to install CrashPlan 4.4.1 (CrashPlan-x64_4.4.1_Win.exe) is proving to be a lot more hassle than it should..
Error messages shortly after kicking off the .msi installation:
CrashPlan setup eneded prematurely because of an error. Your system has not been modified. To install this program at a later time, please run the installation again.
Click the “Finish” button to exit the Setup Wizard.
