Avast Installation Failed

Avast works like most other free antivirus software, working constantly in the background and informing you whether something dubious turns up on your computer during a browsing session. Select the Avast installation direction. Choose Uninstall. Restart your system to reboot Windows 10. Install Avast and run it to reinstall the anti-malware utility on your PC. You must sign into the program to re-authenticate it, if you are a paid user of Avast. Final Words: The above solution should have worked to load Avast UI. If Avast fails to open, check your software and repair it. Follow the following steps; Go to start and type control panel, then launch the control panel. Go to Programs, click uninstall the program and select Avast, then click repair. When you contact Avast Support to report that Avast Antivirus failed to install on your PC, you may be requested to provide a setup log file for further analysis. You can access the setup log from the Avast Setup wizard when you are notified of the error, then copy it to Notepad and save it as a text file to send to Avast support so they can.

Trying to install the latest Avast on a MBA running 10.9.5. No sign of any problems. Machine running fine. I had installed Avast on another machine of his and it did some good, so he wanted it on his MBAir.


The problem, the installer fails at the final stage with a completely generic message that's no help.

Avast Installation Failed Email


Looking at the console log, lead me to believe a couple things:

- Perhaps it was tripping over a permission problem.

- or perhaps it wasn’t happy that Chrome was not installed.


One specific log line item says (which might be the key if someone can interpret, my Google searches haven't been able to untangle):

'CoreServicesUIAgent: Error: qtn_file_apply_to_path error: Read-only file system'

So, here are the things the DIDN'T solve the problem

1) repaired permissions

2) installed Chrome

3) repaired home permissions

4) restarted

5) turned off Gatekeeper

6) redownloaded installer

7) ran Disk Repair, which led me to booting into Recovery Mode to fix a couple directory structure mismatches.


Any ideas what else it could be tripping up this install?


I don’t have enough experience with Avast to know whether or not this is an “Avast problem”, but I certainly have more experience with installing under Mavericks to say Avast is most likely the culprit here.


I suppose I could give up on Avast and go to ClamAV, but he’s “sold” on Avast. I realize there are other virus protection solutions and I realize there's some debate on whether or not anti-virus software SHOULD be installed on a Mac. Just looking for suggestions on the installation problem itself.

Have submitted a ticket to Avast, but only a canned response so far.
