So i'm writing this to help others achieve INPA on their windows 8.1 64bit laptop.
I've done it, verified it works.
FYI The installation of the first package will be in C:\ so you know
I'll be hosting it on my dropbox for a little, if someone can mirror it, I would be grateful.
First download this INPA package.
https://www.dropbox.com/s/mn6n4bhej826ear/www.bmwpost.ru_INPA.rar?dl=0
unzip, go to programinstallation\setup.exe , run it in xp compatability mode press next all the way through then reboot
once rebooted go back into the unzipped folder, go to referenz2006 and then run the exe in that folder. choose english and then UK preferences , only update the first two. complete it.
No need for reboot
Next you need the e39.eng and e39.ger files to place in your INPA\CFGDAT
https://www.dropbox.com/s/ufov0h935ya6j74/CFGDAT.rar?dl=0
this is CFGDAT zip , take the e39.eng e39.ger from this and place it in the folder above.
here is the e39 sp daten files. replace the ECU folder in the ediabas folder , replace the daten CFGDAT and SGDAT in the NCSEXpert folder with the ones from the zip.
https://www.dropbox.com/s/w8v1b8ysm2x7t5v/E39.rar?dl=0
Go into INPA\CFGDAT and double click inpa.ini , change any of the lines you wish to represent which F button it corresponds with "E39" for all three lines . FYI our S62 engine is hidden nicely under shift + f9 for old models under e52. You can also use the e39 profile under Shift + f9 for old models if you don't want to edit your INI file
Example :
F6 = E39
F6_Text = E39
F6_ARCHIV = SGBD_E39
save it close it run inpa enjoy!
Feedback needed incase i missed a step, thanks!
Edit: If i'm missing any files let me know, i sort of want to revive the whole INPA tutorials since there aren't any written for 8.1
