I have solved an ISTA-P problem that happen in case of improper shutdown of windows 7 32bit, ISTA–P version 3.61.5.000.
With help of users > darckreign1984 and AutoExe3219 I was able to discover following. 8 hours of labor.
If you see a screen, that ISTA-P folder does not exist anymore, just check if there is a folder named Dataprocurement in following two directories :
If there is no such directories, you must copy them from another location in the PC. The location is :
C:\Users\Administrator\AppData\Roaming\BMW Group\BMW ISTA-P Loader V6.1F\18.104.22.168\dataprocurement
There ate the two separate directories that simply have to be copied to the directories listed above. Then just start the loader and fill up the form with a data that you want. Then, from the loader page choose BMW cars and you are good to go.
Remember. Never try to shut down the PC before the loader is completelu shut down.
Make a backup of the critical locations to be able to make a restore in case of such accident.
Maybe this thread could be a sticky one.
