[wix-users] failing to elevate privileges on Win 10 - WiX 3.9r2

Wed Oct 5 13:55:53 PDT 2016

Is your bundle digitally signed?  My suggestion would be to submit the bundle to the AV vendor first.  Are you using WixStdBA or a custom BA? Also, upgrading to 3.10.3 to avoid the drive by download DLL hijack would be highly recommended.

It may be possible to have burn "retry" but it seems that Panda is doing something in a non-standard manner where it is preventing another process from working while it does "its thing" with files.  It also seems in this case that the bundle retrying probably wouldn't accomplish anything, as repeated manual attempts failed.

Panda antivirus is the issue.  Is there a recommended method of dealing with this?  I hate to add text for all my users advising them to turn of their antivirus, when it probably only applies to a very small percentage.
So:

1. Is there a way to make the installer work around this issue without the user having to know about it?
2. If not, is there a way to catch this error and give an appropriate error message ("turn off your antivirus")?
3. Or, anything else you suggest?

Here's what the tester sent me, including his suggestions at the bottom:

Bingo, but it was kinda strange figuring it out:

I disabled Panda Antivirus.
I uninstalled MC.
I ran the MC installer. (Same install file I'd previously used.) There was no problem!

I uninstalled MC.
I restarted Panda AV.
I ran the MC installer.
There was still no problem, even with AV running. Was it really AV then?

I tried to uninstall MC.
I got that error message on uninstalling!

I disabled Panda AV.
I tried to uninstall MC.
It uninstalled this time.

I restarted Panda AV.
I waited a minute to make sure it was really doing its thing.
I ran the MC installer.
It installed fine, despite AV running.

I uninstalled MC.
I waited longer.
I ran the MC installer.
It failed.

I ran the MC installer repeatedly.
It failed repeatedly.

I disabled Panda Antivirus.
I ran the MC installer.
There was no problem!

So I'd say that it's definitely something the AV is doing. Perhaps it is checking out a newly-unpacked file right while the installer is trying to do something with the file. And evidently, it isn't necessarily doing this kind of live checking out until it's been running for several minutes, making it tricky to diagnose.

Anyway, I'd suggest having something in the installer to alert users to the possibility that this error can be caused by AV live checking. Ideally, the error message that pops up could suggest that the cause is an AV program.
If that's not feasible, you could at least put a warning on the first screen (before they click the Install button) that an AV program can cause the installation to fail.
