Lexia in VM crashing every time, also crashes the host

Unread post by selma_true »

Hello! I'm rather stumped with Lexia for some time now. I bought in Poland a Diagbox set (they advertised it as "silver" variant, for whatever it's worth) and all worked pretty well with my previous Peugeot 307 2.0 HDi.

Now I have Citroen Xsara break 2,0HDi, facelift and I just can't get this to work properly. I can get from Diagbox to Lexia, do a inital scan of the car and look around in menus for a minute or two, then either Lexia crashes or the whole PC crashes.

I tried re-installing, tried earlier versions starting from Diagbox 7.02 all the way to 7.57 trying different versions between that. Tried routing the cable through an USB hub, without USB hub, VMWare virtual machine, VirtualBox virtual machine (I found a link to ready virtual machine here on the forums). Only thing I haven't managed to do is to run the Diagbox on bare metal, since I can't get a 32-bit Windows to install on my laptop. I have a netbook with 32-bit Windows 10 installed, but can't get diagbox to activate there after installation (always error 0) no matter what I do.

Any ideas what still to try? I start to be pretty stumped at this point. I need to activate cruise control and try to code my keys since remote fob is not working, but I'm pretty afraid to do anything else than read fault codes because the VM crashes every time.

I can't help wondering if you have a dodgy OBD2 socket which causes various problems. Check there are no pins loose or bent and no dodgy connections on the back of the socket. :)
I used to be indecisive, now I'm not so sure!

You can install Diagbox natively on a 64 bit system, but for cars before about 2008 you need to install a late version of the software. See viewtopic.php?t=74136

Thanks for the tip! I'll try to have a look.

My car is from 2004. After going from 406 to 307 I decided to move back to older cars. Around 2000-2005 is the sweet spot for me :--))

How about the socket in the car? :)

Need to also have look if that's looking knackered.

If all else fails I'll borrow another pair of cables from a mate next month - though I'd like to get to the bottom of this issue before that. I'm going a bit crazy with trying to install different versions of software, fighting with the activation after reinstall just for it to crash when I get to the car :-D

I think I forgot to mention in the OP - the VM I've been running has always been XP 32-bit, SP3 generally. I didn't manage to get Win7 running in VMWare VM - plenty of USB issues. Though maybe I'll have a crack on the Oracle VirtualBox. Maybe there's a ready VM image of Win7 with Diagbox floating around somewhere? I only found a ready XP image.

Your best bey would be to install a standalone Lexia (not Diagbox) on an old XP laptop

That's something I was considering - but the installation files that came with my cables are the whole Diagbox set. Haven't seen a standalone Lexia installation around, though I didn't exactly look or it either.

I found a Win XP VM image that had Lexia and PP2000 installed separately. Tried running Lexia through that, worked for a couple of minutes but crashed as well. I'll try to find Lexia to install on bare metal (no VM), but so far looks like it's not so easy to find since everywhere I only see Diagbox.

The problem is, lexia will not run under VM ware,
I run diagbox 7.57 with lexia inside on windows 7/32 without any problem.
If it's use this one an older car, lexia start automatically depending on the vin number.

OK I understand - so the next step will be to try and run Lexia on bare metal. If anyone knows where I could get my hands on the installation files, do PM me.

Windows 10 32-bit is unsuitable for diagnostic installations because only a 32-bit share is possible and LEXIA 3 requires a 16-bit system. If you install on WIN 10 64-bit, only DIAGBOX (32-bit) will work and LEXIA or PLANET (16-bit) will not be installed in a diagnostic-capable manner.

All Diagbox software versions up to 9.23 only work with a Windows version that also has a 16-bit component.
Software 7.57 requires WIN 7 32-bit prof. or XP prof. Sp3 so that older vehicles can also be diagnosed with LEXIA.

Starting with diagnostic software 9.24, PSA has converted all vehicles to 32-bit, so that LEXIA also works on 32-bit.
This means that WIN 7 32-bit, WIN 7 64-bit, WIN 10 64-bit and WIN 11 64-bit are suitable for this software.
WIN 10 32-bit or XP cannot be used with 9.xxx.

Conclusion:
Either install the stable 7.57 on WIN 7 32-bit or alternatively on XP,
or install any 9.xxx (from 9.24) on one of the above operating systems.
