ISTA+ 4.57.30 installation problem

I follow this instruction exactly, but STEP 5 i get lost. Any options to add registy key wont appear...

Click to expand...

• ISTA+ 4.57.30 diagnostic only.reg
• ISTA+ 4.57.30 full programming.reg

1. Go back to your extracted archive and look through all subfolders — especially config, tools, registry, or reg folders — for .reg files.
2. If you find them, right-click → Run as administrator → confirm the merge into registry.
3. If the .reg files are simply missing from your download, then the archive you got is incomplete. You'll need to re-download the full package or find the missing registry files separately.

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\BMWGroup\ISPI\ISTA

• DataPath — pointing to your ISTA data folder
• IconPath — path to ISTA icons
• PdZDataPath — path to PSDZdata (for programming mode)
• OperationMode — value that switches between diagnostic-only and full programming

1. Double-check every folder in your extracted archive for .reg files — use Windows search for *.reg inside the ISTA folder tree.
2. If they're truly missing, post back with a screenshot or list of what's inside your config folder and the root of the archive, and we can help you figure out what's missing.
3. Also mention where exactly you downloaded this package from, so someone with the same version can confirm the correct file structure.

I have reg files yes but instruction advices me to choose operation mode first in step 5. How?

Click to expand...

• Option A — Diagnostics only: Double-click the .reg file named something like ISTA+ 4.57.30 diagnostic only.reg
• Option B — Full programming: Double-click the .reg file named something like ISTA+ 4.57.30 full programming.reg

1. Decide what you need — if you only need to read codes/diagnostics, go with Option A. If you need ECU coding/programming (and you have PSDZdata from Step 6), go with Option B.
2. Right-click the matching .reg file → Run as administrator
3. Click Yes when Windows asks to confirm the registry merge.
4. Done — move on to Step 6 (if you chose full programming) or Step 7.

Je suis scrupuleusement les instructions, mais à l'étape 5, je suis bloqué. Aucune option pour ajouter une clé de registre n'apparaît.
Des conseils ?
Merci.

Bonjour, pouvez-vous m'aider ?

• Un problème de communication partielle avec le KOMBI (combiné d'instruments)
• Une connexion via ENET/ICOM qui ne lit pas correctement certaines valeurs
• Un souci de compatibilité de la version ISTA avec le véhicule

• Connexion via D-CAN uniquement — beaucoup de ces modules (Headunit, KAFAS, ZGW, etc.) sont sur le réseau Ethernet du véhicule et ne sont pas accessibles via D-CAN/OBD seul. Pour un F39, il faut idéalement un ICOM ou un câble ENET pour accéder à tous les boîtiers.
• Ou un problème réel sur le véhicule (bus MOST coupé, etc.) — mais 22 défauts de communication en même temps, c'est plus probablement une limitation de l'interface utilisée.

• Quelle interface utilisez-vous ? (ICOM, ENET, K+DCAN ?)
• Quel est le problème exact que vous essayez de résoudre sur le véhicule ?
• Est-ce que ces défauts de communication sont votre question, ou avez-vous un autre souci ?

Bonjour,

D'après vos captures d'écran, ISTA+ 4.57.21 fonctionne et est connecté à votre BMW X2 sDrive18i (F39, B38, 2018). Le diagnostic tourne, l'arbre des boîtiers électroniques est visible, et le scan des défauts est terminé.

Quel est exactement votre problème ?

En regardant vos images, je remarque plusieurs choses :

1. Kilométrage aberrant
Le kilométrage affiché est 4 294 967 295 km — c'est la valeur maximale d'un entier 32 bits non signé (0xFFFFFFFF). Cela signifie que la lecture du kilométrage ne se fait pas correctement. C'est souvent lié à :

• Un problème de communication partielle avec le KOMBI (combiné d'instruments)
• Une connexion via ENET/ICOM qui ne lit pas correctement certaines valeurs
• Un souci de compatibilité de la version ISTA avec le véhicule

2. 22 défauts de communication
Tous vos défauts sont des "Aucune communication possible avec..." — HKL/HKFM, Headunit, ZGW/BCP/IPB, GWS/BZM, KAFAS, caméra, module remorque, etc.

Cela peut indiquer :

• Connexion via D-CAN uniquement — beaucoup de ces modules (Headunit, KAFAS, ZGW, etc.) sont sur le réseau Ethernet du véhicule et ne sont pas accessibles via D-CAN/OBD seul. Pour un F39, il faut idéalement un ICOM ou un câble ENET pour accéder à tous les boîtiers.
• Ou un problème réel sur le véhicule (bus MOST coupé, etc.) — mais 22 défauts de communication en même temps, c'est plus probablement une limitation de l'interface utilisée.

Pouvez-vous préciser :

• Quelle interface utilisez-vous ? (ICOM, ENET, K+DCAN ?)
• Quel est le problème exact que vous essayez de résoudre sur le véhicule ?
• Est-ce que ces défauts de communication sont votre question, ou avez-vous un autre souci ?

Avec ces infos je pourrai mieux vous orienter.

• What exact ISTA+ version is installed now? (you mentioned 4.57.x earlier—exact build if possible)
• ICOM Next firmware version (from ICOM Toolbox / device info)
• Did you install ISTA+ as “ISTA-D” or “ISTA+ Diagnostic” (and did you install PSdZdata for coding/programming too, or only data for diagnostics)?
• Are you connecting via ENET/Ethernet (ICOM), not via K+DCAN/ODBD?
• When you connect, does ISTA show the KOMBI + all modules, or only a subset?

• For a diagnostic-only job, you still must have correct “PSdZdata/ISTA support” installed for your vehicle.
• If you installed programming data as well, make sure the folder structure matches what your ISTA expects.

• uninstall ISTA+
• reinstall
• reinstall PSdZdata (the correct one for your ISTA build)
• reboot

• Services related to ISTA/EC-APPS must be running (ICOM communication and DB services).

• you’re not using a “virtual adapter” only
• the ICOM adapter has correct permissions
• there’s no VPN/driver conflict

Ah, I see what you mean now — the guide says "Add registry key" and lists two options (A or B), but doesn't explain how to actually choose between them. It's simpler than it looks:

You just pick one and double-click the corresponding .reg file:

• Option A — Diagnostics only: Double-click the .reg file named something like ISTA+ 4.57.30 diagnostic only.reg
• Option B — Full programming: Double-click the .reg file named something like ISTA+ 4.57.30 full programming.reg

That's it — there's no separate menu or UI to "select" the mode. The .reg file is the selection. It writes the appropriate registry values that tell ISTA which mode to run in.

Steps:

1. Decide what you need — if you only need to read codes/diagnostics, go with Option A. If you need ECU coding/programming (and you have PSDZdata from Step 6), go with Option B.
2. Right-click the matching .reg file → Run as administrator
3. Click Yes when Windows asks to confirm the registry merge.
4. Done — move on to Step 6 (if you chose full programming) or Step 7.

Note: You can always switch later by running the other .reg file — it will just overwrite the previous registry values.

Please make sure your ...

• Start with a clean reset of the ISTA user/config
  • Close ISTA completely.
  • In Windows Explorer, go to your ISTA data folder and delete (or rename) the ISTA config/cache folders, then re-open:
    • C:\EC-APPS\ISTA
    • If present: C:\EC-APPS\ISTA\cfg, C:\EC-APPS\ISTA\logs, C:\EC-APPS\ISTA\temp (or similarly named)
  • If you’re not sure which folder is safe, tell me your exact install path and ISTA version.
• Reinstall/repair ISTA prerequisites (very common after failed installs)
  • Run the ISTA installer again but choose the option to Repair (if available).
  • If no Repair option: uninstall ISTA, then reinstall.
• Verify PSdZdata is present and matches ISTA version
  ISTA will often fail to start if PSdZdata is missing or mismatched.
  • Confirm the PSdZdata installed folder exists (commonly under your EC-APPS data directory).
  • Confirm you installed the correct pack for your ISTA build (Diagnostic vs Full).
• Reset non-standard ISTA configuration
  • Open ISTA configuration (if you have an ISTA “configuration tool” / “ISTA settings” shortcut).
  • Make sure connection/interface settings are not pointing to a removed component.
• Check Windows permissions
  • Run ISTA as Administrator.
  • Make sure EC-APPS folders aren’t read-only and the account has full access.
• Check the ISTA log / error details
  This message is generic; the real reason is in logs.
  • Please find and paste the last error lines from ISTA startup logs.
    Usually located under: C:\EC-APPS\ISTA\logs (or similar).
