Causality unistalled itself and will not reinstall (on win 11)

On my Win 11 - Surface Pro 8.
I have been using causality for a few years. Today, while out at a cafe, causality just uninstalled itself after only a few minutes after I had started the application.
(I only use a hotspot off my phone for internet)

I am home now and Re-installed the latest version and it still will not launch. It doesn’t exist in the app Registry. When I type causality in the search, I only get an option for an UNINSTALL.

It is working on my WIN-10 PC at home (at the moment)

How do I resolve this issue on my surface Pro?

Hi,

If it literally uninstalled itself, then this sounds more like an anti-virus reaction, if the install directory is literally gone. And then when you try to install it again, it gets immediately quarantined.

You should know that signature based anti-virus is only 80% effective, and usually never effective against new threats, so they have to guess based on app behavior, and sometimes they guess badly.

I do remember there was someone three weeks ago who got a warning, and Windows wouldn’t let him install it. So we called people up and tested on fresh Windows machines (this was Windows Defender), and none of them had the problem. And later, this person seemed to get it working.

The reality is that when we make new releases, there’s a period where only a few people in the world have run it, and that makes Windows Defender nervous. So, are you still having this problem?

I did, just recently, get it to reinstall. But only after I deleted the App directory on my C: drive.
Just the Program Files dir. And then when I tried an install, it worked.

It still has to be some kind of malware protection. The installer simply overwrites contents of the Causality folder in Program Files. There’s nothing sophisticated going on, it’s like dragging a folder on top of another folder.

But it is explained by an anti-virus putting a quarantine on files. And it’s one of those things that’s impossible to investigate, because in this case, it’s only happening on exactly one machine, possibly two. It’s fuzzy logic. Anti-virus are largely vulnerable to new attacks, so the best they can do is guess, and different machines may guess differently.

I’m glad it’s working! We’ve tried before to get flagged by Norton (for no reason at all to be clear), and suddenly everybody thinks you’re a crook!
