How to Update BMW ISTA Software?

Updates are released 2-3 times a year and distributed via download links or sent on a BMW FOB USB drive (as ISTA-P files are sometimes too large to download if you have a slow internet connection). These updates are 100% optional and can be skipped as they are non-sequential, meaning you’ll install the latest update without having to purchase the interim updates.

• Remove ISTA-D from your machine and clear up some space, Browse to C:\Program Files (x86), find and select the folder ‘Rheingold’ and delete it.
• To remove ISTAP and clear more space, Browse to drive C:\, find the folder ‘apps’, and delete it.
• Delete both from the Recycle Bin.
• Now proceed to install ISTA-D, reboot, and then ISTA-P. If you install any of these, right-click on the exe file and run as administrator. As a best practice, also right-click on the exe file for each BMW ICOM Software before running as administrator, as I mentioned above, and check if Windows ID is blocking it, make sure you unblock it, see below:

DO NOT uninstall the currently installed software from the Programs and Features Control Panel.
