The issue is that if you install UI.Vision from the unpacked Chrome extension, Chrome assigns it a different extension ID and the XModules does not find it.
There is a way around this by editing the XModule installer and changing the list of allowed extensions IDs, but the by far easier solution is to use Firefox. Firefox does not change the extension ID of local (non-store) installations. Thus we recommend Firefox for offline use:
(1) Download & install Firefox or Firefox Portable
(2) Download & install the UIVision XPI file from here: Archive - UI.Vision RPA Software
(3) Download & install the XModules (you have already done this step, no need to reinstall)
In step 2 the installation is easy: You only need to drag and drop the XPI file onto Firefox’s addon page and you are all set. Once you installed that, the XModules should show up in the Firefox extension.
If you want to use Chrome and/or Edge please insert the new extension ID in the ZIP installer as described here, then re-run 1install.bat (Windows) or 1install.sh (Mac/Linux).
