Installing LF Webtools extension into new Edge browser hit and miss

Installation and Upgrades Laserfiche Web Client Laserfiche Cloud Integrations

So, it's been random enough that I've just lived with it over the last year but now after replacing multiple of my own PCs with fresh Win 11 boxes I am struggling with some PCs installing the Web extensions for LF into Edge just fine, and one or two PCs just seem to refuse to install into Edge. Chrome is fine and it installs there just fine but it's like sometimes it doesn't even try to find Edge. I try uninstalling, rebooting, reinstalling, reinstalling without reboot, etc etc.. Sometimes eventually it'll get installed but it seems frustratingly inconsistent.

Does anyone have a surefire way of either forcing it to detect and deploy to Edge or at least some way to coax it to work? Once installed, I generally have little issue, it's just the installer doesn't seem to go looking for Edge.

EDIT: I'm downloading the latest LfWebOffice110.exe, run the latest O365 software, etc. The office plug-in works fine. It's that it doesn't have the browser extension to allow me to open with Office apps. It always prompts me to download the "Laserfiche Office Installation".

It doesn't show installed in the Edge native extensions page or Chrome extensions page (in Edge). It does show installed just fine in Google Chrome itself, it just don't use that browser.

Yes, plugin.laserfichelocalhost.com should resolve to 127.0.0.1.

Can you clarify exactly what you're trying to install? WebTools Agent is not a browser extension, it's a per-machine installation. The old "Laserfiche Web Access Extension" is no longer necessary.

Right. Since it sounds like you are on version 11, the extension should no longer be necessary. Instead, you should see Laserfiche Webtools Agent in Task Manager. But it sounds like maybe that isn't working properly? Are there any errors in the browser console?

Ok, I stand corrected. Thanks for that clarification. I will stop looking for a browser extension. I am simply trying to install whatever is needed so I can open an Office document in the full app. Currently when I try to do that it says I don't have the web tools installed.

I look in Task Manager and see Laserfiche Web Tools Agent running in processes.

Looking at the dev console when I get the prompt to download the plug-in I see this:

That URL plugin.laserfichelocalhost.com does not resolve to an IP from command prompt. Is that supposed to be added to a HOSTS file so it resolves to 127.0.0.1 or something?

Thanks. I went and manually entered that into the HOSTS file and magically everything started working. Apparently however the installer normally does that must somehow fail in some situations/installations. I guess if I know the workaround I can manually repair it where it doesn't install correctly.

plugin.laserfichelocalhost.com is an actual hostname that we maintain a dns entry for, so the expectation is that it should just resolve correctly without needing to do anything to the hosts file. I wonder if that dns lookup is blocked on the customer's network? I could see an IT admin thinking that a dns response of 127.0.0.1 could be potentially malicious.

Modern security software likely is going to start blocking this DNS in the future. DNS entries that resolve to 127.0.0.1 are likely going to look like malware behaviours. Our network utilizes this type of next-gen security software so likely was preventing this resolution.
