Hi,
This a follow up and a bit of clarification since my response to Walt has been picked up.
Firstly clarification - I've not used Walt's batch file to invoke from a 3rd party application. I'm using DXO and ACDsee and, as far as I can see, I can only invoke .exe files rather than .bat files.
So, now for a bit of follow up. And apologies but the precise order of what I've done is lost in the mist of exploration and button presses. I started this morning by starting from the desktop shortcut I'd created yesterday.
I then moved on ...... When I came to explore V2 this morning I tried to invoke V2 from DXO but got a message along the lines of (sorry - I've been fiddling for a couple of hours so can't remember exactly) "can't access". Or something like that - the upshot is I couldn't invoke V2 from DXO. Since I now know where the V2 app is I went to the folder to find I didn't have permissions that I had set up yesterday - so I think I couldn't start V2 by double clicking the .exe in that folder - even though the desktop shortcut I'd created yesterday worked fine. I've now regiven myself permissions and am getting V2 to invoke via DXO and ACDsee but - I have now had a couple of requests to re-enter my licence/account details. I have no idea why my permissions changed overnight. anyway, I've done a couple of restarts and things seem to be working OK at the moment.
As far as Walt's batch file is concerned - I can confirm it launches V2 from my desktop.
Hope this helps and apols if earlier lack of clarity has confused.
Regards
Martin
