How To Use Inpa E46

I have an BMW INPA cable myself but used to install it on a XP laptop. Recently some forum members are asking is it possible to use it on Windows 7 system? If yes, how to? After much research, I have finally got it working and hope this can help any of you. I only used it on my E46 M3 (2004) and so I can confirm that it works fully with this car but I cannot guarantee if it works on other BMW cars.
I purchased my cable from Careucar. It came with software in a mini CD. This is the specific cable that I purchased and that I can confirm works:

Connect the cable into a USB port on your PC. The PC should automatically search USB cable drivers. Follow the prompts to install the driver.

Right-click on the above and select ‘Properties’, then click on the ‘Port Settings’ Tab and then click on ‘Advanced’.
Change the ‘Com Port Number’ entry to ‘COM1′.
Change the ‘Latency Timer (msec)’ to ’1′.
Click on ‘OK’ and close all the windows, restart your PC to confirm all the changes.
Extract the contents of the downloaded file ‘INPA-6.4.3-full.rar’ and you’ll find a NRG file. This is a CD image that you’ll need to either burn to a CD or extract to a folder using a tool such as ISOBuster.

Select ‘Environment Variables’ and then verify that the System Variables ‘TMP’ and ‘TEMP’ both contain the path ‘C:EDIABASBin’ within the ‘Value’ string – for instance “C:WindowsTemp;C:EDIABASBin”.
Extract the contents of the downloaded file ‘INPA_502_Updated.rar’.
You’ll use the contents of this archive during the next three steps.
From the above extracted file set, find the file ‘Step 1_ Install BMW Tools.exe’, right-click on it and select ‘Properties’.
Click on the Compatibility tab and change the dropdown to Windows XP SP3 as the Compatibility Mode, also tick ‘Run As Administrator’, then click ‘Ok’

Locate the file ‘C:EDIABASBinobd.ini’ and copy this file into your Windows folder.
Edit the file ‘C:EC-APPSINPACFGDATINPA.INI’ in Notepad, locate the section that starts with ‘//F3′, remove the slashes at the beginning of the three lines of text, and amend any instance of ‘F10′ to ‘E46′.
10.In theory, you’ll now have an INPA icon on your desktop and Start Menu – right-click on it, select ‘Troubleshoot Compatibility’, it’ll select ‘Windows XP SP3′, click ‘Next’ and ‘Save’. This step is not necessarily required, however it apparently provides a little more stability for the application.

Now, with your interface connected via the USB port (remember NOT to plug the cable into any port other than the port that you originally configured the cable with) – and the other end connected to your car, fire up INPA and hopefully you will have a working diagnosis tool.
