There is a prompt when selecting to scan, first it must detect that you have installed one of the 3 scanning programs, then it will let you continue. How does this technology work? You can access the local computers installed programs via some technology in modern web browsers? It seems someone found a way to block access to the installed programs for Chrome but I don't even know the name of the setting.

How does Laserfiche Cloud detect what programs you have installed on your operating system?

We use WebToolsAgent to detect whether other plugins are available.
What is the actual issue you are seeing?
I don't see any browser technology called WebToolsAgent. Is this propriatary software that is installed with the scanning installer?
So bascially, we have Web Scanning and Desktop Scanning installed, it is listed as an installed program on the operating systems Programs list.
However when you go to scan in Laserfiche, if it detects that the software is not installed it puts up a barrier to coninuing and instead askes you to download the installer. This is what is happening, so the user can not scan because the website "thinks" that they have not yet installed the software.
Laserfiche WebTools Agent is one of the components that gets installed with Scanning or the Office plug-in that allow the web browser to detect and launch other plugins. It's a replacement for the older browser extension technology of versions pre-10.4.2.
There are a couple of cases where you may run into the behavior you're describing:
- Laserfiche WebTools Agent is not installed. If that's the case, you should be able to download it and install it from the web client's management page. Or you could re-download and install Scanning from the web client, which will also install WebTools Agent.
- Laserfiche WebTools Agent is not able to connect. This may happen on terminal server environments where more than 3 users are running it concurrently. There's a status for Laserfiche WebTools Agent in the web client's management page. If it's listed as running, then this is not your issue.
- Laserfiche WebTools Agent is fine, but your Scanning version is out of date compared to the version that the web server has available. You're being prompted to upgrade.
Ok, I found Web Tools Agent on my machine. I am having them check the problematic machine, yesterday we were only looking for the Scanning software under programs.
Yes, Scanning also need to be there, but it's not enough by itself. I'd be curious how they installed it if it turns out that WebTools Agent is not present.
It is showing Web Tools Agent in the programs list. So it must be disconnected from the browser somehow. Does Web Tools Agent have an interface we can look at?
From the web client, open the Options page and look under Advanced. You should see something like this:
The status should listed as "running" and one port needs to show "connected".
Perfect! Having them check this
