Hi All, nice to meet you. I'm Adam, usually called SecondDimension when I'm hanging around in the Internet. I live in the UK. The cat in my Avatar is my real-life cat.

I've been making games on and off as a hobby for a few years, but only got serious about it the last 6 months. I've taken part in the past two Ludum Dare Game Jams and loved the experience. I learned a lot in those two 48 hour competitions, and got a great confidence boost from placing fairly well in the rankings (top 80).

I've used a few IDEs including GameMaker and MMF2, but I've just purchased Construct2 as I wanted an hassle-free method of outputting HTML5 games. So far I'm finding it robust and easy to use.

I feel like I have at least one great game hidden somewhere in my brain, I intend to drag it out kicking and screaming and make you play it

One other thing that forgot to put on the list; I uninstalled Mikogo. Although I still think that using Driver Sweeper was what solved it for me...

I changed from Nvidia to ATI graphics about 18 months ago, and Driver Sweeper found the old Nvidia drivers still on my machine. I suspect that deleting these fixed the problem. Perhaps the Steam version has some conflict with Nvidia drivers on Vista 32bit?

OK, the good news is that I've managed to stop this error occurring on my system. I still get a load of strange DOS boxes, flickering and so on, but the export works and the games are playable when uploaded.

The bad news is that I'm not entirely sure what fixed it, as I spent an hour changing and uninstalling things, after which the problem seemed to be solved. I can narrow it down and say the fix must have come by doing one or some of the following things:

* Setting Windows Explorer to show hidden files & folders

* Verifying Application Cache for CS2 Within Steam

* Disabling Steam In-Game Community

* Uninstalling Steinberg CuBase and associated drivers

* Uninstalling GameMaker Steam version (in case of sabotage)

* Uninstalling All Non-Valve Games from Steam

* Uninstalling Skype Click-to-Call

* Uninstalling EA Download Manager & all games that need it (Spore etc)

* Disabling Every Plugin, AddOn and Theme within FF & IE (left Chrome alone)

* Using Driver Sweeper to remove any outdated graphics drivers (Nividia)

(edited for spelling)

Just to test last night I opened a command prompt and disabled DEP completly. Rebooted, and it didn't make any difference, so that's not the issue. I guessing this must be a Vista issue.

Some other things I might try when I can get home; verifying game cache through Steam, disabling Steam Community in-game.

ViZiONEER: Have you changed your graphics card anytime in the last few years? This is the only thing slightly out-of-the-ordinary that I have done with my machine, switching from nVidia to ATI. This was about 18 months ago though, and hasn't caused any other problems so it's a long shot. Just trying to think of anything common between our setups

I wonder if you tried the standalone free version if that would be OK for you as well. Plus, do you have any issues with previewing in Firefox? I bet this is something so obscure

— Well other than the that fact your CS2 seems to get through the export with no crashes, I'd say that problem is almost identical to mine. I get lots of png errors as well (with compression on) and amongst those boxes I do get the same "cannot open file" error. I also get the "application couldn't be initialized properly (0xc0000005)" error if I turn off the png compression.

Have you tried uploading and testing the exported files, are they all OK?

I'm currently uninstalling my other Steam applications to see if that helps. Plus I'm running through clean-up processes with Glary Utilities, Driver Sweeper, Malwarebytes etc. I'll see how I get on

OK, I do understand that it doesn't seem to be a common problem, it's so frustrating when you have these crashes and nobody else does. I know you guys are a small company and there's probably little more you can do from your end. I'll do a full reinstall of my OS, of all my drivers, of Steam and so on in a systematic fashion, to see if I can fix the problems. I'm willing to make the effort as the software really is a joy to use up the point of exporting. Thanks for responding anyway

I don't think I have anything particularly exotic, I only recently did a clean install of Vista.

The thing that concerns me here is that the standalone version is fine, nothing is clashing with that or causing issues with my current setup. If that didn't work either then I would agree 100% that is was definitely my issue. There must be some difference between that version and the Steam version that is causing me the problems.

Hi Ashley, thanks for the reply. I have done 3 things to futher test this, the first is to run a full Malware scan, results check out, so all clear there. The second thing I did was to add pngout.exe to the DEP "Allow List". This unfotunately had no effect, as I still got the same DEP error from pngout.exe despite it being in the allow list.

The third thing I tried was your suggestion of setting png copmpression to none. This didn't give me the DEP error from pngout.exe, but I still got the "Java Platform SE Binary has stopped working". I also then get a new error which reads "the application failed to initialize properly".

After further testing with different browsers I also noticed that if I try to preview any project in Firefox, I get all the same errors and crashes every time. IE and Chrome are fine. I disabled all add-ons in Firefox, same result.

As before, both exporting to HTML5 and previewing in Firefox continue to work perfectly in the standalone free version??

Are there any error logs or anything that would be helpful? I can post screenshots of the errors if you need me to.

Yes the workaround I mentioned actually is no good because of the limitations. So I can't export my projects at all

I just reinstalled everything through Steam just in case, but the problem persists. I also tried the free version through Steam, no luck. Standalone continues to work.

Is there any way to perhaps transfer my Steam license to a standalone one?

I recently purchased Construct 2 through Steam and I'm having issues exporting projects. The 'contact us' section on the website directed me here. I have filled out the bug form below, but I feel this overview might be more helpful to initially describe the problem:

    * I have the paid personal license through Steam

    * I use 32-bit Vista Home Premium

    * I have the latest version of my graphics card drivers

    * I get a DEP Error and a Crash whenever I try to export any Project

So far so boring, BUT, there is a twist at the end of this story... Having tried and failed to get the export working with my paid Steam version, as a last resort I downloaded the free standalone version of Construct 2 and installed it. The export works perfectly with no errors, every time.

This for me rules out graphics drivers as a potential issue, and points towards either Steam, or the Steam version of C2 being the issue. As I've used Steam for years with no other issues I thought it best to raise this as a Construct 2 bug

As a workaround, I can use the Steam version to create games, save the projects, then switch to the standalone free version to export them, but obviously this is not ideal. As a footnote I'd like to say that having used other IDEs, Construct 2 is just ridiculously good, so if I can get this sorted then that would be great. Thanks

BUG REPORT

Link to .capx file:

This is an exporting issue that affects any and all .capx files I've tried it with, so I'm not sure this is relevant. For the purposes of testing I used the included 8 direction movement example.

Steps to reproduce:

1. Open any .capx file in C2 through Steam version (paid personal license)

2. Export Project to HTML5 webstite

Observed result:

1) The following errors are generated:

    "pngout.exe has stopped working" (this is generated multiple times)

    "Data Execution Prevention has Closed pngout.exe

    "Java(TM) Platform SE binary has stopped working"

     Construct 2 Crashes

Expected result:

Completion of export process with no errors

Operating system & service pack:

Vista 32-bit Home Premium (99% sure it's on SP2, will confirm when I get home)

ATI Graphics 5000HD series (latest drivers)

Construct 2 version:

r119 (Steam)

NOTE: Problem is repeatable at every attempt to export using paid Steam Version, but problem does not occur at all on the standalone free version of Construct 2
