CYBERMiiN

Ah ok thanks, didn't know that, I had only just (re)installed it for the first time in a couple of years about two days before the W10 update screwed everything up, glad it appears to be sorted for now....until the next time Cheers.

Hi, well I have been playing around with FSX again now that Microsoft have "Fixed it" and no more Child window errors however I was just looking at configuring some settings and I was running resource Monitor and it appears that FSX is now running all 8C/16T not sure if it was doing this before the "fix" or not though, anyhow it is running smoothly again now and I have just grabbed a couple of new GA aircraft to fanny about in. Cheers.

I have found with FSX:SE that I don't seem to get the problems now that I have removed ALL (both of them) my add-on aircraft and airports (ORBX freeware ones), at least that was yesterday so it may change again today I was getting the child window / unsupported operation error even just using the default aircraft before (with the add-on ones installed). I still have REX Texture direct/soft clouds+ HD Airports (Skins) and ORBX FTX Global Base/Vector/OpenLC Europe installed but no other add-ons or mods and as I said yesterday for the four or so hours I was testing it I did not get any errors (though this was probably just luck). It is strange how these last couple of updates only seems to affect FSX (at least in my case), I have not had any problems with any other software I use. Cheers.

Really ? the 64bit as well ? wow, what the hell is going on I ask myself ? Sux...

I not sure formatting Windows 10 will fix it, after reading of other people on here formatting multiple times and still having the issues, I wiped my FSX + Add-on installation and thought at first it was cured, but no, it returned

Hi, glad it is only the 32bit version of P3D, think I'm probably going to get P3D v4.1, time to leave the relic of FSX in the past and move to a today FS Of course I'm sure there will be problems with that as well but a change is as good as a rest.

Well good luck with that I've given up at the moment and am now listening to some music, think I might fire up 'Order of Battle - Winter War' no child window or unsupported operation errors there (I hope). Cheers.

Hi Dio, Well I myself do not have any PMDG add-ons but was getting the errors with the default aircraft plus my Alabeo C172 Cutlass and an old FS2002/2004 freeware Jet Provost, have not been using any other aircraft. Anyhow I have now got a fresh install of FSX, my Cutlass and Jet Provost, REX 4 Texture Direct + Soft Clouds, REX HD Airports, all have been tested in DX9 mode, no W7/W8 compatibility or run as admin, have been clicking on the menu bar changing weather/time/season, creating flight plans, saving flights, changing aircraft all working great for a few hours and I kid you not I went to exit my last flight to come back on here to report my findings and *BAM* 'An unsupported operation was attempted' clicked ok and found myself back on the desktop......NNNOOOOOOO That's it I give up.

Not really sure that Steam can do anything about it, think it is more down to Microsoft and/or Dovetail.

Hi, Ok, so I have been testing my fresh FSX install (still using DX9) with a couple of add-on aircraft now, the Alabeo C172 Cutlass which I was having the child window / unsupported operation errors with before and also tested a freeware FS2004/2002 Hunting Jet Provost, flew both of them for approximately an hour each, clicking away at the menu bar loading the map, changing weather/time/season, creating new flight plan etc and no more errors as of yet and didn't have a single issue with either of them (well apart from the Jet Provost getting through its fuel at an alarming rate). I am now going to start re-installing all of my REX+ORBX add-ons one at a time before I think about the DX10 Scenery fixer and cloud shadows, but so far so good. Cheers.

Hi, Ok so I thought I would post an update, last night I uninstalled FSX and all add-ons and wiped every single reference I could find to them then re-downloaded FSX from steam. Firstly I updated to the new nVidia driver (388.43) that was released yesterday then rebooted. Ran FSX with totally default flight, clicking on menu functions, map, changing weather etc. all fine no problems so I exited the flight, changed some menu settings (display/autogen/clouds) rebooted, launched default flight again clicking on menu (without pausing FSX) even created a new flight plan, changed season, changed weather and still no errors or CTDs, Great At this stage I have made no adjustments outside of the FSX menu what so ever, no changes to the exe. (no run as admin or W7/W8 compatibility mode) I flew around for an hour, landed, saved flight. Made some more changes in the display menu to make it look better (though no DX10 preview) and rebooted. Ok so now I made one change outside FSX and that was to turn on vertical sync for FSX in the nVidia 3D settings panel, and that was the only change I made (can not stand screen tearing ). I launced FSX again, loaded my saved flight, flew around for another hour, clicking on menu functions and changing settings and not one single error message in sight and FSX is running completely stable. At the moment I am happy that I have not managed to trip it up or break it entirely however as of yet I have not installed any add-ons or fixes and am enjoying flying around over the English winter desert that is the FSX default in a Mooney with a glass cockpit So now I am going to try a couple of add-on aircraft first as they will be easier to remove and clean up if they break FSX (hopefully), will report back later. Cheers.

Ah, I was wondering if it may have been an issue with the FSX exe, had altered mine to run in administrators mode but I had not tried to run it in W7 / W8 compatibility mode. I am now downloading a fresh copy from steam after trawling though my 5 SSDs / HDDs deleting every single reference to FSX or the many add-ons etc I could find, then I'll start the painful, tiresome task of installing / tweaking until it breaks again

Yes, I think the reason is because every single person on the planet has a different computer installation

Hi, just out of interest do you have the DX10 scenery fixer installed ? as I was unable to get the Just flight PA-28R Arrow III demo to work for more that about two seconds after the windows update until I uninstalled the DX10 fixer however then all my aircraft would veer to the left on take off so I have given up and wiped my FSX install

Yes I get paid in two weeks so I think I will probably take the plunge with P3D v4.1 as well I also don't have any issues with FSW (just booted it up earlier to test) other than I don't go a lot on the graphics or presentation but that's another kettle of fish and I don't want to start any flame wars about that, plus Most of my add-ons should be compatible with P3D (REX/ORBX and my Alabeo Cutlass)... Hopefully Cheers.

Well, I did not have any problems with FSX until the 'Creators update' and all that managed to create was chaos in my FSX installation (oh and my desktop boots nice and fast now - thanks Microsoft) so I guess my old grandma was right, there only so long you can prop up a dead horse before it falls over entirely Cheers.

Hi there, yes I installed it earlier, it did not make any difference to the errors.

Well here's the thing...... I think I have solved the issue now with the 'child window / unsupported operation' errors after I uninstalled the DX10 scenery fixer and cloud shadows, however now apart from having ugly yesteryear graphics, all my aircraft now have their left aileron up and the right aileron down so as soon as I take off the aircraft will veer to the left straight into the nearest building I have reset all the controls to default and this is happening with my flight stick and my xbox pad so I am going to uninstall all the add-ons and my FSX installation and re-download a fresh copy, if I still have issues after that then I am going to treat myself to Prepar3D professional for xmas (early).

Ok wasn't sure and was almost expecting a 'n00b' comment to be in there as well and no I wasn't trolling, just trying to get my FSX working again, anyhow my joy was short lived as right after I posted to say it was ok now I fired up FSX, loaded my Alabeo Cutlass in free flight, clicked to show menu bar, clicked on show map and "'BAM'" 'An unsupported operation was attempted' error again, clicked 'OK' twice and there I was back on my desktop. I have now uninstalled the Alabeo Cutlass as well so I have no add-on aircraft (though I do have lots of expensive REX/ORBX add-ons installed as well as DX10 Scenery fixer) if I have one more Child window / unsupported operation error I will be removing and re-downloading a fresh install of FSX from steam

Hi, sorry I'm not sure if you are trying to be condescending, it appears I do not have a major problem with my computer after all as I removed the A2A Accu-Feel add-on from FSX and now it appears that my computer has been magically fixed no more errors ! Thanks for your help, cheers.

Unfortunately for me it appears I don't have anything to roll back to as I have already done a disk clean-up.

Ok thanks for that.

Well I have just installed the KB4051963 update and rebooted and it has not fixed the child window or unsupported action errors for me....grrrr

Hi everyone. Well, I bought the Alabeo C172RG myself today (17th November), installed into FSX:SE and low and behold non working FuelFlow and DME Radio, my first Alabeo product (and my first payware aircraft) and possibly my last, if I had known about this issue before I would not have bought it and probably won't buy another Alabeo product until (or unless) it is fixed, unfortunately them seem to make a lot of GA aircraft that I want.
