I have Interlogix TruPortal systems out there.

The web interface requires flash. Does anyone have any PC and iOs based alternative suggestions for me?

I can enable flash in a few browsers but most are Adobe based which will no longer be supported after the 12th. I am hopeful that a third party will fill the void for legacy situations.

Sorry to derail....but...

Does no-longer-supported mean it literally stops working or that it will work for now but wont be updated?

Adobe embedded a kill switch in recent updates and a Microsoft update uninstalls Flash. So more in the it-stops-working department.

Completely disabled.

Update on this...

I had to use an older laptop. In my case it was running Windows XP. I diabled automatic updates and used Chrome which has flash on the version I had.

I was able to log into the TruPortal system and update to the newest firmware which abandons flash for HTML.

Worked like a charm. Two more to go.

It also works sometimes to just override your pc date settings to a date when flash still worked. Did this a recently and just setting my laptop date back a year allowed me to access a flash based configuration page for a device.
