I have followed all the instructions. I downloaded both files, I have 3.5 with 2.0 framework and DirectX runtime. I tried running the program first on my own computer, which runs Windows 7, then I tried on my moms computer which is running Vista, and got the same exact problem. Is there something I overlooked? I couldn't find any other information on the issue.

The Unitool is woefully outdated and shows no signs of being updated anytime soon, I would recommend you try another program.

Could you show us what's behind the details button? Are you trying to open a specific file, or just run CTU? CTU may not have been updated recently, but it still works perfectly well.

It just happens when I run the program, period. I get the message as soon as it loads.

CTU is missing various options and is ruining some CC because of it. A good example is how it still doesn't have a necklace category, so people making new accessories that should be necklaces aren't marking them as so because the CTU has never been updated and they don't even realize that the category exists.

You should never advise using oudated programs, whether they "work properly" or not. They're still outdated.

You said to use another program - so what do you suggest? CTU is still very useful, and for those of us who don't want to use TSRW there's nothing else that does what it does. I don't think telling people not to use it just because it's 'outdated' is helpful unless you have a better alternative.

I really don't know much about creating clothing, however, can't you just change the values in S3PE after creating in CTU? Using the values as shown in Sims_3:0x034AEECB^wiki and edit the Clothing resource in the CASP? While the Necklace category doesn't show you can manually add (9) in there.

Yeah, Lunie, that'd work perfectly fine. I was thinking of hunting down the value to do a quick tutorial, actually, so thanks for saving me the time . Of course TSRW is also useful in many situations - but I prefer to keep the bloat down so I stick to CTU & S3PE.

What about the error details, kmercer?

Yes, you can. But are people going to do it? No, they aren't.

The simple fact is that CTU has not been updated in ages. It's missing functionality. And because of that, encouraging people to use it isn't a good idea.

TSRW is a good alternative. It can make packages and sims3packs, it can access any and all clothing content from any expansions/stuff packs, and in general has a hell of a lot more functionality and is much easier to use. Even better, it's updated enough that it's not missing any basics. There aren't options to choose the newer expansions, for example, but you can still choose them under any of the other expansions (Meaning selecting the Late Night folder when prompted to select the Ambitions folder), and it works fine.

I had the same issue. Vista and Windows 7 have security settings that block many unkown Apps from running w/o 1st changing these settings. Find the Unitool App (where you placed it in your computer) and right click. Go to "properties" and down at the bottem you will should see an option to "Unblock" your app. Click that and you should be able to run the program. Note: It should be just under the check boxs for "Read-Only" and "Hidden". Hope that helps.

Same thing happens to me aswell... but my error is with Daboobs:
