Sims 3 Qtcore4.dll Issue

in Featured,Sims 3 Guides,Sims 3 Technical Stuff

After running Sims 3 on this system since the game was released and then installing World Adventures and High-End Loft Stuff shortly after they were released, I’ve had no issues with the game.

Until today.

Today I wrote about uninstalling all of my Sims 3 games because of Launcher issues which I assumed were caused by custom content.

I uninstalled it all and then started reinstalled the games, starting with the base game and going from there. At least, that was my plan. After I got done installing Sims 3, of course the game prompted me that I need to update the game and since we’re on patch like 10 million or something now, I expected that to take a while.

And then I got an error saying my laptop was missing the Qtcore4.dll.

Well, what the hell is that?!

Of course, I consulted my on-site tech support – Google – and found all kinds of helpful sites which offered FREE Qtcore.dll downloads in a convenient zip file and didn’t I want to go ahead and not only download their super awesome FREE Qtcore.dll and their FREE computer scanner but also subscribe to their AMAZING  program thingie?

I mean, it seemed like a really good deal. Right?

Yeah. Not so much.

Since it was a .dll error and I have had experience with nasty ass .dll trojans, I did download a reputable free registry cleaner [Abexo] from CNET and ran that. I’m not quite sure if it helped anything but it made me feel better.

I was just about to tell technician Google where he could put his crappy suggestions when I got the brilliant idea – only brilliant because it worked – to search around on some Sims 3 forums and actually got lucky on my first try…first because I already had the tab open and I’m damn lazy.

The solution is on Mod the Sims and you’ll probably have to have an account to read it but I’ll summarize what you need to do in case you don’t feel like signing up…though that is a rather handy account to have.

Ready for a bit of interesting though annoying news? You know how I blamed custom content for my Launcher screwing up? Sorry, custom content. I should have blamed the Launcher since that was my issue and that’s what’s going on for you.

How do you fix the Sims 3 Qtcore4.dll issue?

Uninstall your EA Download Manager and then reinstall that bitch! I know, right? How easy is THAT solution?!

I just went to my Control Panel and clicked on the handy-dandy “Uninstall a Program” and got rid of it. There are more complicated instructions at that Mod the Sims link dealing with “orphaned” files and such but just uninstalling the program worked for me and it took everything when it left.

Good riddance…except now I had to reinstall the EA Download Manager and I’m sure you’re wondering, “Where the hell do I get whatever the heck you’re talking about?!”

EA has been nice enough to provide a link to fix their broken piece of crap and when the program is reinstalled, that mystery missing .dll should go back to its happy little place deep within the confines of your computer…where it should have been in the first place.

That’s what I did and it worked for me. No downloading of mystery .dll files from shady websites required.

Happy Simming!

*Edited to add: Apparently I have bigger issues and am killing the whole thing all over again. I’ll update again when I’m done. Blarg.*

*Edited again to add the final solution. You can find how finally I fixed my Sims 3 game here. Woot!*

Oh wow, this was so great for me! thanks. now the damn launcher works... sick and tired of sims baffles and all there damn new updates they come out with. (:

your freakin awseome <3 ; love the way you make it easy to understand & actually funny !

Thank you!  You're awesome.

thankkkkkkyouuuuu!!!! so muchhhh! 

Thank you so much!  Amy, you are a Godsend!  Me and my Sims are rocking and rolling thanks to you!!

 Thank you! Trying this now. xD

I had to reinstall the game then got the message again, so, like you, I consulted Google and glared at all those shady links but luckily this post was among the first few searches! 8D

Thank you so much! You are the best!

Super happy it helped! :)

thank you sooo much! my sims 3 has been JACKED for 2 months cuz i thought my computer was just too slow to run the night life expansion pack and since i hadnt backed up my saved games and was too discouraged to start over i just quit playing and i'd been getting that stupid Qtcore4.dll error message and had no idea what the hell it was even for let alone how to fix it so i googled and it brought me to your page. it was awesome to find out that not only could i get rid of that annoying ass message with a simple re-install but that it would fix my sims as well, you really made my day

Ugg! Been there and done that. Nothing worse than a borked game.

Okay, first off Oh Em Gee.. Loved this article. Found it very helpful to my QtCore4 reeree file that has been missing. You have no idea what I have gone through lol. Correction, yes you have but I have uninstalled my game 5 times. This last time is when I got a new message about the Qtcore file... now that it popped up with a dll on the ending I was able to in the words of another sim3ster " use my online tech support Google". I was able to search for the file at least figure out what kind of file it was, and where was its mother, aka program that it went to. And boom i found this page. Not only do I love my S3 but I can say I love ya in a Sister kinda way. So Kudos to you girl. You Rock...!!!!

The "Oh Em Gee" part kills me. Just so you know.

A-MAZING. Why couldn't technical support just tell me I needed to do that?! You rock :)

Super glad I could be of help. :)

Thank You So Much, You Are Amazing!!!

Thanks so much, i was so annoyed with it not working! I sent a message to EA and they told me to delete everything and start again! So irritating. Glad you came up with a simple solution that only takes two minutes, thanks again.

Where would I back up my files if I dont have an external hardrive? And where do I get the EA Download manager from? I also only have sims 3 on my comp, do I need the others to do this? I've been playing without them, just using sims3.

Thanks again for all your help ^-^

Link for the EADM is: http://eastore.ea.com/eadm

And as far as backing up w/out the external hard drive, you can just copy the files to your Desktop or wherever you want on your computer--assuming you have the space.

Wow you are awesome! and super fast with your replies ^-^
Thank you, a friend of mine and I are going to give it a shot now. Hopefully I can come back with a lovely positive comment =)

Keep it up!! <3

Thanks so much from New Zealand =)

I must have really lucked out. Your site was the first one I checked out. Thank goodness. I haven't played my S3 in a while and got the itch to control the world again when I got this crappy message! Stupid thing. Thanks for making me a goddess again! :)

OMG thank you soooo much!!!! Its working fine now!!!

Thank you so much!! I didn't think it would work since nothing ever works for me but it did!!

Thank you thank you!!

Oh my GOSH, thank you. It worked!

THANK YOU SOOOO MUCH!... I almost shit my pants when I saw something was wrong. My game ended up installing the new manager before I read the end of your instructions but I uninstalled and did what you said anyway. lol. Needless to say with out you I would have been very sad. So... THANK YOU. You rock my socks.

Seriously, you saved my LIFE! I encountered this problem and was completely confused! That is, until I read your artcile :). Re-installing the DL Manager worked like a charm for me. Thanks so much for your helpful (and hilarious) post!

Thank you!
I wanted to play The Sims 3 so bad today, but, lo and behold, my QtCore4.dll was missing! After a few hours I hadn't found a solution. But then I found your site, and 15 minutes later, I've got everything back to normal!

I am ever sooooooo grateful, it worked. You do what I do, and actually your suggestion on my google was the first on the list, so you saved me massive headaches and soo much other stuff that you went through.... Again thank you heaps and heaps!!!! You ARE a SUPER HERO!!!!!! get your cape on!!!! lol :*

Hey thanks!!!! Hope it works!!!! OMG if it does, thank you soooooo much!!!!!

thank you so very much, i greatly appreciate it. i was getting so frustrated and kept installing and uninstalling the game and just going nutzzz. your site really helped. i had given up on the sims. but all it normal thanks again

Thanks for sharing this excellent article. (as always, btw)

I've never left a comment, and rarely I comment on other blogs but I read you everyday, and often more than once a day. I'll try to leave few words here and there.

Thank you SOOOOOOO much. You seriously helped. I was messing around with it for about 2 hours before i got the brilliant idea to come check it out on google.

Yep, nice blog. Keep it that way.

You make blogging look like a walk in the park! I've been trying to blog daily but I just cant find writing material.. you're an inspiration to me and i'm sure many others!

Loved the comment above I think that you are correct and we should do something about it.

You are amazing. I was totally bummed out, and wondering if while I'd installed the cc something had gone wrong when I was lazy enough to click on the first thing I found when searching Google, and voila it actually worked.
Thanks so so much. Now my friends and I can get back to playing grown-up Barbies, it's really what it is lol.
Thanks

ThankYouThankYouThankYouThankYouThankYou

a LOT!

My father gets mad when something's wrong with the sims (maybe because I let the computer crash because I wanted to reinstall the sims 3 and so he had to recover the computer and losed all of his (illegal) programmes, oeps)

So I wanted to fix this myself and it worked! :D

Maybe you could edit the page title Sims 3 Qtcore4.dll Issue | Sims 3 Gamer to something more specific for your blog post you create. I loved the post withal.

I love how you said your "Damn lazy"! I had to lol at that, so with that in mind, how are you going to handle all the files that you now have to add to the DEP thing? It's like 3 or 4 files per expansion, plus the base game. That is becoming a major pain!

I only had to add the executable files and it's all of the bugs and glitches are a pain in my ass - and apparently yours as well.

But, it's become painfully obvious EA isn't in any hurry to address some of the common issues everyone seems to be having.

Oh. Well. Just think how tech savvy we're going to be when this is all said and done. ;)

I know right?! Now Late Night with it's crazy NPC's (they won't take care of their basic needs) and them getting stuck behind buildings, and the crashing launcher, I'm having to learn way more about the mechanics of this game than I ever wanted to know. I just wanted to play, not fix their glitches. Maybe I should send them my time card and a bill! ;)

You're a genius! Thank you! You solved my mystery issue. =)

Thanks!!! and this made me laugh haha :)

Super! Helpful AND funny. ;)

Hey sweet, thank you very very much! OBRIGADA!!!
