If you're installing manually and having issues then use Sedoy's installer instead. I and many others have used it and it 100% works so you either have an issue with your downloaded files or there's something else wrong with your PC

You can still update to the 4.38 service data but using the 4.37 program.

And how exactly do you do that ?  because i have been reading about this here on this forum. But one person says this the other says no you have to do it this way, and there is nobody who post the correct way how to do it , so i am still waitingh to update the DSP and BLp.

Best regards

What do you need to know - how to update 4.37.4x to 4.38.3x?

Yes

This is what I did and it worked for me (assuming you have ISTA Launcher Console downloaded and the folders set up correctly) - maybe some of these steps can be combined but as it worked for me I'm happy!

1) Install Sedoy 4.37.4x standalone

2) Download and put the following files into the ISTA_Store\Downloads folder:
BMW_ISPI_ISTA-META_SDP_4.37.42.xml
BMW_ISPI_ISTA-META_SDP_4.38.10.xml
BMW_ISPI_ISTA_DELTA-SDP_4.38.10.istapackage
BMW_ISPI_ISTA-BLP_4.38.10a.istapackage

3) Run IstaLauncherConsole

4) Delete all files from ISTA Store\Downloads folder apart from BMW_ISPI_ISTA-META_SDP_4.38.10.xml

5) Download and put the following files into the ISTA Store\Downloads folder:

12) Run IstaLauncherConsole

EDIT for 4.39.1x:

13) Delete all files from ISTA Store\Downloads folder apart from BMW_ISPI_ISTA-META_SDP_4.38.30.xml

14) Download and put the following files into the ISTA Store\Downloads folder:

25) Delete all files from ISTA Store\Downloads folder to clean up (or you can leave BMW_ISPI_ISTA-META_SDP_4.39.25.xml in there ready for the next update)

26) Done - Service data should now show as 4.39.25!

Thanks for this break down. I managed to go from 4.39.20 to 4.39.36 for SDP data.
