Lexeri Windows app

Hand over a document for checking

Your application hands over a document by starting Lexeri.exe with the absolute path of the file as argument. If the app is running already, the running instance takes the document; otherwise the app starts with it. The install folder is in the registry under HKLM\Software\Lexeri GmbH\Lexeri, value InstallPath.

using System.Diagnostics;using Microsoft.Win32;
// The app's install folder (default: C:\Program Files\Lexeri\)using var key = RegistryKey    .OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64)    .OpenSubKey(@"Software\Lexeri GmbH\Lexeri");var folder = key?.GetValue("InstallPath") as string;
if (folder != null){    var start = new ProcessStartInfo(Path.Combine(folder, "Lexeri.exe"));    start.ArgumentList.Add(@"C:\Projects\Manual.docx");    Process.Start(start);}

The same in PowerShell:

$folder = (Get-ItemProperty 'HKLM:\Software\Lexeri GmbH\Lexeri').InstallPathStart-Process (Join-Path $folder 'Lexeri.exe') -ArgumentList '"C:\Projects\Manual.docx"'

What happens next:

1. The app uploads the document to Lexeri as a temporary file. Your file stays unchanged.
2. The sidebar opens the check form; users who are not signed in sign in first.
3. Choose the termbase, language and filters, then Start term check – the matches appear in the sidebar.

The app checks one document per call and ignores further arguments. In Explorer, users get the same path via Send to → Lexeri (on Windows 11 under Show more options).

Check selected text with a hotkey

While the app runs, it checks selected text from any application: select the text, press Win+Shift+L and the sidebar shows the text for checking. The hotkey can be changed in the menu of the tray icon under Hotkey: Win+Shift+L, Ctrl+Shift+L, Ctrl+Alt+L or Win+Shift+K.

How the app reads the selection

1. UI Automation: the app reads the selection through the TextPattern of the focused element. The clipboard stays untouched.
2. Copy: if UI Automation returns nothing, the app sends WM_COPY to the control and then simulates Ctrl+C. It restores the previous clipboard content afterwards.

It takes up to one million characters.

Installation & requirements

The app is installed as an MSI package for all users of the computer into C:\Program Files\Lexeri\. Package and program are signed by Lexeri GmbH.

Current version: Lexeri-1.0.14.msi.

Managed deployment

For software deployment (e.g. Intune or SCCM) the package installs silently. It needs an elevated context.

msiexec /i Lexeri-1.0.14.msi /qn /norestart /l*v install.log
# Other install folder; WebView2 is deployed separatelymsiexec /i Lexeri-1.0.14.msi /qn /norestart INSTALLFOLDER="D:\Apps\Lexeri" SKIPWEBVIEW2CHECK=1

After a silent installation the app does not start by itself. On its first start it sets up autostart with Windows and the Send to → Lexeri entry for that user.

Updates and diagnostics

• The app checks for updates at launch and periodically and installs signed packages itself; manually via Check for Updates… in the tray menu.
• Log files: %LOCALAPPDATA%\Lexeri\logs\, one file per day, kept for 14 days.
• Registry: HKLM\Software\Lexeri GmbH\Lexeri with InstallPath and Version.
