3. Installation Procedure (Standard Reg-Standalone Method)

Most installations of 4.39.20 utilize a "Standalone" or "Reg" package which bypasses the need for a BMW server connection.

Phase 1: Prerequisite Setup

1. Enable .NET Framework 3.5 and IIS via Windows Features (Control Panel > Programs).
2. Install the .NET Framework 4.8 offline installer.
3. Run all provided VC++ redistributables found in the installation pack's "PreReq" folder.

Phase 2: Application Installation

1. Mount the ISO or extract the archive containing the ISTA files.
2. Locate and run setup.exe (typically located in the ISTA\InstProg directory).
3. Select "Standalone" as the operation mode.
4. Accept the license agreements and allow the installer to extract files to the default directory (usually C:\Rheingold).

Phase 3: Database Integration

1. If the database (PSdZ) is included in the installer, the setup will prompt for the data location.
2. If using a separate database file (SQLite), you must copy the SQLiteDBs folder into the installation directory (e.g., C:\Rheingold\SQLiteDBs) and point ISTA to it via the settings menu upon first launch.

Phase 4: Post-Install Configuration

1. Navigate to C:\Rheingold\Triton\current\config.
2. Run the ISTAGUI.exe.config file (if modifying settings).
3. Apply the "Reg" fix (a registry file usually included with the download) to ensure the software detects the database correctly.
4. Launch ISTA. If it prompts to upgrade the database, allow it.

4) Install prerequisites

1. Install .NET Framework 4.8 and required Visual C++ redistributables.
2. Reboot.
3. Install interface drivers and verify device appears in Device Manager.

4.1 Set ISTA to Offline Mode

• Open C:\EC-Apps\ISTA\Configuration\ISTA\Settings.xml
• Change:

  <OfflineMode>true</OfflineMode>
  

Phase 5: Activation (License Bypass)

Since ISTA 4.39.20 requires a paid BMW subscription, you will use a local license emulator.

1. Copy ISTA_License_Generator_v2.0.exe into C:\EC-Apps\ISTA\TesterGUI\bin\Release\.
2. Run the generator as Administrator.
3. Enter your system’s Hardware ID (displayed in the generator). If it is blank, run ISTAGUI.exe once – it will create a license error and show the HWID in the log.
4. Generate a license.ini or istagui.lic file and place it in the same directory.
5. Open ISTAGUI.exe as Administrator. You should see “Licensed to: ISTA Internal User”.
