1. download SuperOrca(free)
2. edit .msi file with SuperOrca (set LaucherNotFound and NotCalledByLaucher--> 0)
3. Execute .msi file and install (all necessary files have to be in the same directory)
4. extract datapackage file and copy extracted SQLite databases to your SQLite databases folder of your installatio directory
5. edit registry for x64 system it's:

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\BMWGroup\ISPI\ISTA]
"DataVersion"="3.50.10"

Start ISTA

a popup will appear that reminds you to check ISPI process blabla and that data can only be stored on local drive.. Just ignore.

No need to use different ISTAGUI.exe files or something similar

I was going to ask what the procedure was to edit the msi file because i was not sure of the way i did it and then i came across your post and its how i did it, except the editing part, where exactly do you put the zeros? In what cell(s)? Thank you!
