[Simple]

For DiagBox 7.xx, you can use your name or any other name, but if you have had the previous failures on the same Windows XP installation, I would strongly advise you to use "DBCleaner v101a" making sure you run it as Administrator.

The below is a write up I published sometime back on this forum but got deleted when the site lost all data since October 2014.

If your notebook currently runs Windows XP 32 bit, you can install Lexia applications directly on it. However, many of the currently available notebooks are unlikely to come with Windows XP; in which case the best way would be to shrink your last partition by about 40 GB and create a new partition to install windows XP 32 bit on it, then the Lexia application. Nevertheless, you can run Windows XP (and many other operating systems) within a Virtual Machine installed on your current notebook’s OS; luckily, they are mostly free and readily available. I have tried both methodologies and both work well, I have preference to the Virtual Machine because I still have access to my other operating system (in fact I am writing this whilst performing another test). One can also change the amount of memory (RAM) or computation power (CPU) as need be, you can clone it, and if you do not like it, you can delete it.

Let’s Start:

Ensure that all files and folders names do NOT include spaces or funny characters, example: “Folder_1or_file_5” and not “Folder 1 or file 5”. If possible, convert all your media to ISO format ensuring the media is laid at the root directory and NOT inside another folder, Example: if you mount the DVD ISO it should be “G:\installation_material” and NOT “G:\Lexia 3\Diagbox\installation material” (where G is the arbitrary DVD drive letter).
1- Install VirtualBox, the Extensions and Guest Additions, ensuring the following:
a) The Hard Drive controller must be IDE.
b) Create a preferably fixed hard drive more than 24GB. Dynamic also works.
c) Connect the Windows ISO through the Settings -> Storage -> Optical Drive.

2- Install a clean Windows XP Pro SP3 and activate it and install the following tools:
a) All necessary drivers.
b) Setup a network adaptor
c) Install Mozilla Firefox
d) Java 7
e) Winrar or 7zip
f) Virtual Clonedrive (not needed for VirtualBox)

3- Connect the Lexia USB interface to the computer so that VirtualBox identifies it:
1. Click on VirtualBox Settings, USB, Add a new USB filter and choose the code representing Lexia interface.
2. Leave the Lexia interface connected throughout the whole installation process, if Windows asks to look for drivers then just cancel for now.
4. Disconnect the network cable.
5. Create a blank file named version.txt in C:\ i.e “C:\version.txt” (This step may not be necessary with newer DiagBox versions).
6. Mount the DiagBox 7.02 ISO and run the setup, go through the process. At some stage, "new hardware found" window will appear, do not choose to search automatically for drivers, you may cancel it or just manually select the driver that should now be available.
7. Once done, start DiagBox and when prompted for activation, choose the "manual activation" option, fill-in information as per the provided instructions, usually (Customer Code, Address, Post Code and Car Phone) you can enter any characters or numbers.
8. Start DiagBox again it will run the update for 7.02.
9. Install the update package/s – I prefer the 7.xx to 7.57. Please note after installing the update you will need to reboot then run DiagBox for the update to be fully installed. At some stage, the drivers may install (if not already installed) where you will get "New hardware found" wizard again.
10. DiagBox (the latest version installed) is now operational.
Connect the USB interface to the OBD-II port on your car, turn on the ignition, and in DiagBox choose your car, insert your RPO and work away.

Attached is the "DiagBox V7.01 file and V7.02 to V7.65 updates" document, posted originally by Scarymistake. I hope the Administrators change the title of this thread to 7.65 and to add this document to the first post to help others.
