License is valid for all ISTA Versions for one PC and will be rejected if change Mainboard, update BIOS, activate Bitlocker, reinstall/upgrade Windows!!! Make sure that Windows already activated bevore make licenserequest!
VM is not supported!
If license not working check your system with ISTA_SystemRequirements . Maybe you must clean your system, all ISTA regkeys…
From ISTA 4.37.22 need renew license(only if WinFasta as Name in DealerData), simple remove license from registry and make new request. Reason for that is that BMW removed unused Brands from code.
Remove Key „License“ from:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\BMWGroup\ISPI\Rheingold
or
HKEY_CURRENT_USER\SOFTWARE\BMWGroup\ISPI\Rheingold
