Lenz L1-USB on Windows 7. Help needed!

The PC does recognise my Logitech USB 'Trackball' mouse, and it 'sees' the LI-USB but that has the yellow mark on the icon. Further investigation (Or in my case, much blundering about and cursing!) reveals that "Windows cannot find the driver". I've tried the 'look on the internet for suitable drivers' option, no joy, also tried the 'look on the computer' option but again, despite having unzipped and installed the updated (V3.6) drivers, Windows can't find them. Shame there isn't a 'Try Specsavers' option!
Trying another tack, last night I was fortunate enough (I hope!) to acquire a Lenz 23151 LAN/USB unit on Ebay, complete with leads and CD for £100 (New these are £165) so I am hoping that this may be the answer rather than spending the rest of my days literally banging my head against a wall in trying to get the 23150 unit to work for me, as I have better things to do with my time (and models to build/complete!). Once that arrives, I may well be back with more daft questions, so "Watch this space!"
In the meantime, many thanks for all your help and suggestions, you have no idea how much I appreciate them.

Thanks for your assistance Robert. I assume that the version you referred to will be on the included CD with the 23151. To be honest, I have no idea what a LAN port looks like, but I'll research it and look to getting the crossover cable too. Thanks again.

I had a visit yesterday evening from the 'friend of a friend' who has a degree in computers. 20 minutes and it's all up and running!!! He pointed out that since I don't intend (at least for the present) to be wanting to control the layout from my iPhone, I didn't need to bother with the ethernet setup, though I have already fitted a PCI LAN card to the PC and have the crossover cable but for the moment I'll stick to keeping it simple. Now I have to decide "do I invest in DCC point control or stick to switched analogue control?"
Decisions, decisions!

Hi Splitpin.
My Lenz setup is V3.6 also, the CD which came with the LI-USB is a 2015 edition so fairly up to date software-wise. I've no block occupancy in place or in fact even thought about, but already have JMRI Panel/Layout/Decoder Pro on the PC, point motors are mostly Seep PM1's with the auxiliary switch which I have utilised to control colour light signalling, a few Hornby ones where I can't fit Seep's (due to under-layout support struts in the way), but these have changeover relays wired so as to switch signals also. I've never run my layout to a timetable (I'm not that organised!), don't really plan to anyway, and can't foresee automated computer operation as part of the plan. As I have 43 points on the layout, I'd need about 8 of the Lenz switching decoders which aren't cheap, so it would be a slow changeover exercise if I went down that route. Soldering isn't a problem, as I've been soldering firstly as an electronics 'dabbler' as a kid, and later as a professional Electrician for 60 years now, and have progressed to brass/white metal loco kitbuilding over the last couple of years which has meant that, to my shame, I have only rarely run any trains at all for about the last 18 months since I find kitbuilding very absorbing and interesting, though I'm not even approaching the standard of Rob Pulham on this forum.
My main problem has been that as I have little knowledge of Windows PC's (I use an iMac anyway) and have had no formal training on any computers, having been inducted at the "Bumble Through" school of computer studies, I've had difficulty in working through what is supposedly a 'Plug-and-play' format when the LI-USB didn't 'Plug-and-play' as it should have. Fortunately, all seems to be operational now.......maybe I should leave things as they are!
