I have installed an old version, can I reinstall over it without removing the previous version?
Yes you can. But if you run into problems, remove the old version(s) installed.
I get a warning from my antivirus software. Can I proceed with the use of the software safely?
Yes you can. Depending on your antivirus software, you may get an antivirus warning when installing LIFEx. For instance, Kapersky EndPoint Security 10 for windows detects an PDM:Trojan.Win32.Generic. See: http://support.kaspersky.com/fr/faq/?qid=208282629
Each and every version of LIFEx is carefully checked for any viral contamination and you can install it without any risk. You can disconnect your antivirus software during the installation to avoid that problem.
LIFEx can’t be opened because it is from an unidentified developer. Your security preferences only allow you to run applications from the Mac App Store and from identified developers ?
Two options to solve it:
- Right-click (or control-click) LIFEx icon and choose “Open”
- Click the “Open” button at the next dialog warning to launch the app anyway
- Launch System Preferences from the Apple menu
- Choose “Security & Privacy” and then click the “General” tab, followed by clicking the lock icon in the corner to unlock the settings
- Look for “Allow applications downloaded from:” and choose “Anywhere”
- Accept the security warning and allow
You can now launch any app from any location or developer
