Ui.Vision RPA Enterprise Installation in Microsoft Edge: Solution for “XModules not found”

Hello together,

i have problems with UI.VIsion RPA in combination with Microsoft Edge and Xmodules.
I have installed the Edge Extension and the XModules, but the xmodules will show that they are not installed.
If i´m using Mozilla Firefox or Google Chrome all is working fine.
I saw already a hint that the group policy allow user-level native messaging must hosts should not have been disabled. We have this policy as well on disabled, but there is also a setting called “Control which native messaging hosts users can use”, which should whitelist the UI.Vision RPA components.
My question is now which com.??? components must be whitelisted to get the xmodules working, without enable the complete messaging hosts.
For Chrome and Firefox the com.??? components standing in the registry, but in edge they are not filled.

Best Regards
Fabian

Hello, normally no extra work is required for Edge. Once the XModules are installed, they can be used from Chrome, Edge and Firefox.

As for your case, is this a standalone PC or are you part of a larger Enterprise network? If so, maybe Edge is blocked from communicating with “native messaging hosts” (this is what the XModules are technically, from the browser perspective).

Can you please check if you have this registry entry:

Software\Policies\Microsoft\Edge\NativeMessagingAllowlist

By default, all native messaging hosts are allowed. So normally there is nothing to do! But if someone set the ‘NativeMessagingBlocklist’ (Configure native messaging block list) policy to *, all native messaging hosts are blocked, and only native messaging hosts listed in here are loaded.

If this happens on your machine, please allow these four native messaging hosts:

  • com.a9t9.kantu.xy
  • com.a9t9.kantu.file_access
  • com.a9t9.kantu.cv
  • com.github.teamdocs.kcmd

Hello,

i´m working in a larger Enterprise Network and Native Messaging is disabled. No Blocklist is configured.

Computer\HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge
NativeMessagingUserLevelHosts = 0

But i´m got an exception in this registry path:
Computer\HKEY_CURRENT_USER\Software\Policies\Microsoft\Edge\NativeMessagingAllowlist
1 Reg_SZ com.a9t9.kantu.cv
2 Reg_SZ com.a9t9.kantu.file_access
3 Reg_SZ com.a9t9.kantu.cv
4 Reg_SZ com.github.teamdocs.kcmd

This Configuration is not working.
So i´m searched for the 4 components in the registry and i´m wondering that with the xmodule installation the 4 components are only installed from you in the registry paths from Mozilla Firefox and Google Chrome. For Microsoft Edge nothing will created. Could that be a problem ?

HKEY_CURRENT_USER\Software\Google\Chrome\NativeMessagingHosts

HKEY_CURRENT_USER\Software\Mozilla\NativeMessagingHosts

HKEY_CURRENT_USER\Software\Microsoft\Edge\NativeMessagingHosts
