ISTA+ 4.57.30 installation problem

Juhnu said:

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.

I am following the instructions scrupulously, but I am stuck at step 5. No option to add a registry key appears.
Any advice?

Hello, can you help me?

• A partial communication issue with the KOMBI (instrument cluster)
• A connection via ENET/ICOM that does not correctly read certain values
• A compatibility issue between the ISTA version and the vehicle

• Connection via D-CAN only — many of these modules (Headunit, KAFAS, ZGW, etc.) are on the vehicle's Ethernet network and are not accessible via D-CAN/OBD alone. For an F39, ideally you need an ICOM or an ENET cable to access all control units.
• Or an actual issue with the vehicle (MOST bus disconnected, etc.) — but 22 communication faults at the same time are more likely a limitation of the interface being used.

• Which interface are you using? (ICOM, ENET, K+DCAN?)
• What exact problem are you trying to resolve on the vehicle?
• Are these communication faults your question, or do you have another issue?

Hello,

Based on your screenshots, ISTA+ 4.57.21 is working and connected to your BMW X2 sDrive18i (F39, B38, 2018). Diagnostics are running, the electronic control unit tree is visible, and the fault scan is complete.

What exactly is your problem?

Looking at your images, I notice several things:

1. Abnormal mileage
The displayed mileage is 4,294,967,295 km — that is the maximum value of an unsigned 32-bit integer (0xFFFFFFFF). This means the mileage is not being read correctly. This is often related to:

• A partial communication issue with the KOMBI (instrument cluster)
• A connection via ENET/ICOM that does not correctly read certain values
• A compatibility issue between the ISTA version and the vehicle

2. 22 communication faults
All your faults are "No communication possible with..." — HKL/HKFM, Headunit, ZGW/BCP/IPB, GWS/BZM, KAFAS, camera, trailer module, etc.

This may indicate:

• Connection via D-CAN only — many of these modules (Headunit, KAFAS, ZGW, etc.) are on the vehicle's Ethernet network and cannot be accessed via D-CAN/OBD alone. For an F39, ideally you need an ICOM or an ENET cable to access all control units.
• Or an actual issue with the vehicle (MOST bus disconnected, etc.) — but 22 communication faults at the same time are more likely a limitation of the interface being used.

Could you clarify:

• Which interface are you using? (ICOM, ENET, K+DCAN?)
• What exact problem are you trying to solve on the vehicle?
• Are these communication faults your question, or do you have another issue?

With this information, I will be able to guide you better.

Click to expand...

• 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.

Click to expand...

• 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).
