Hi!  I love the RXP GTN 750.  In fact I find it hard to fly without it.  I moved over from the F1 version because of ease of configuration and installation/updating of the RXP version. Ever since I bought it it has worked perfectly until today.  I always have one GTN 750 in a pop up window in the top left hand corner.  Then I drag and drop that into a small Lilliput touch screen usb monitor.  It has worked like a dream and is very immersive.  Today however I launched P3Dv5 and the 750 isn't showing.  RXP GTN is showing under add ons in the sim window drop down and the 750 appears under instrument panel as ticked but there is no sign of it.  I changed aircraft but the same thing happened so it would seem this is not a specific aircraft issue. I uninstalled/reinstalled a couple of times within the sim but it made no difference.  Hoping someone can help.  Below is the .ini file for the aircraft I was using.

 

GTN_750_1]
; is the master device if true.
MasterDevice = true 
; aviation db: 0: nav_db2_grm, 1: nav_db2, 2: nav_heli_db2_grmn, 3: nav_heli_db2

usealtcursor = false
; enable touch beyond screen bounds if true (2D only), clip if false (GTN native).
extendtouch = true 
; auto-resize dimension (width,height)
refsize = 
; left mouse button on the screen toggles popup window by ident (ex: GPS_PANEL or 225) (requires SHIFT+left mouse button).
popleft =

popright =

; offset brightness (-100 to +100)
brightness.screen = 0

 

Thanks

Hi,

Can you please post the content of the RXP log files? (see user's manual for file/path)

Hi Jean-Luc,  Thanks for the reply.  I think these are the three files

I should just mention the Garmin Trainer is working and I use a three monitor setup (plus a USB monitor) in case thats relevant.

 

Thanks for your help

First, you might want to use the latest RXP GTN version (2.5.25)

Second, why are you running P3D as-admin?

I recommend to never install nor run anything ‘as-admin’ and to avoid using or purchasing any product requiring you to, unless it is an ‘admin’ tool. There are many reasons for this, like the fact installing as-admin gives special credentials to the installer or the program which files and registry accesses get  ‘sandboxed’ and/or ‘redirected’ by Windows to different locations than when running as a normal user. This leads the installed program to pickup the wrong registry settings or files, or miserably fail once run as a normal user. This also prevents the program to sometimes just read the files/registry because of the Windows access rights preventing to do so.

Another more concerning reason is a bug in a program run as-admin could just wipe out your drive. I tend to illustrate this with: imagine a program deleting all its settings files in C:\MyProg\mySettings\*.* but because of a bug it ends up telling Windows to delete this: C:\*.* (which means delete all files in C:\

It has been more than 10 years Windows Vista introduced the more stringent ‘as-admin’ vs ‘normal user’ and any program today which support tells you to ‘run as-admin’ should be avoided like the plague. Most often people install their simulator in the default location, usually it ends up in C:\Program Files which is a protected folder and they tell customers to run as admin to grant ‘write’ permissions to modify the files. We do manage these cases in our products and our Panel Assistant is perfectly capable to edit the panel.cfg file even if the simulator is in the protected folder. It uses no hacks, just normal Windows programming.

FYI

For several add-on developers this is a requirement. MCE and Ezdok spring to mind. It is also often mentioned to do this by developers when installing their applications. I've begun installing with admin permissions almost by reflex in the fear that the software will not work or install correctly if I did not.

 

Cheers,

Thanks.  That fixed it. Didn't realise there had been an update as I only downloaded in April when I bought P3Dv5.  In fact 2.5.24 was working fine under HF1 until last Thursday so not sure what changed. (Did have a Windows Update?) Its still  2.5.24 on F1 e-commerce site so I just ran my old installer and it automatically updated to 2.5.25.  Slight hitch as P3D did a CTD  twice on scenario screen.  Deleted my P3D.cfg and all is well now and I have my GTN 750 back.  Thanks for the help and for such an indispensable piece of software.  It was the second thing I installed in P3Dv5 (after FSUIPC6).😀

 

As to running as administrator exactly the same as  "howevr" says.

@howevr @rich_cooke Yes I know this and this is why I'm mentioning "to avoid using or purchasing any product requiring you to, unless it is an ‘admin’ tool". You have to understand when running the simulator as-admin, Windows is redirecting some of the file and registry accesses (they are filtered and/or shimmed).

While permitting an add-on not specifically handling UAC limitations to running as-admin, you're also preventing legitimate add-ons from running properly. Think about this: the sim run as-admin, the addon saves a file. Next time you run not as-admin, the file can't be read anymore...

Vista was the first OS introducing UAC and this was more than 10 years ago. There are documented solutions to UAC and we're paying attention to this in order to ensure our customers won't have any issue whatsoever running as normal users.

Having said this, I'm not saying you're doing wrong, I'm just trying to help you making informed decisions (and this discussion will add to the 'searchable' pool of answers for future customers). The RXP GTN/GNS V2 runs fine whether running the simulator as normal or as-admin, but if something breaks, well, you know where to start looking first.
