I tried adware and after I started up the computer the next day I got this lovely msg>
componet comdlg32.ocx or one of its dependencies not correctly registered- a file is
missing or invalid> After some serious searching I got it finally reregistered which reinforces my position of not using anything that doesn't have a support email address

A short, practical summary (adds context to the replies already in this thread)

This error means the Visual Basic common‑dialog ActiveX used by older VB6 programs is missing, corrupted, or not registered — the classic runtime-339 symptom. As noted, re-registering can fix it when the file itself is intact; when the problem appears immediately after installing a utility (as saw with AutoShrink) the installer often failed to place or register the correct OCX. (winhelponline.com)

Quick checklist that fixes the majority of cases

  • Confirm whether comdlg32.ocx exists in the right system folder (64‑bit Windows uses the SysWOW64 location for 32‑bit OCXs; 32‑bit Windows uses System32).
  • If the OCX is missing or corrupted, obtain the signed version from Microsoft (Visual Basic 6.0 Service Pack 6 security rollup) and put the file in the correct folder rather than grabbing random DLL/OCX packages from unknown sites.
  • If the program that needs the control offers a “repair” or reinstall, try that first so the installer can put and register the right files. (winhelponline.com)

Registering and common pitfalls

Register the control using the Windows register‑server utility from an elevated (Administrator) prompt and make sure you register it in the correct 32/64‑bit context on modern Windows. If you hit a registration error that mentions inability to write to the registry or an 0x8002801c type failure, that almost always points to insufficient privileges — run elevated and retry. Microsoft documents the regsvr32 tool and its common error messages. (learn.microsoft.com)

If that still fails

Check for missing dependencies with a dependency tool, run System File Checker to repair Windows files, and perform a full malware scan (an offline Defender scan or a reputable on‑demand scanner) since unwanted installers/adware sometimes replace or block OCXs. Avoid third‑party “OCX download” sites — extract the OCX from the official VB6 rollup or copy it from a clean machine with the same Windows bitness and version. If uncertain, reinstall the affected application or restore from backup. (dependencywalker.com)

you could always get a good, FREE anti virus from, http://sohpos.com free for home users and easy to update, doesn't use up alot of sys res, and doesn't take over!! unlike norton, mcafee etc.

Thanks suRoot, never heard of it but it looks promising. As a sidenote, Norton Anti-Virus isn't incredibly horrible, but Norton Personal Firewall is the worst resource-hogging, registry-editing piece of **** I have ever seen ;)

Norten is pretty bad. I never found it to work half the time and it would not catch virus's that where months old even after a update! It also slowed down everything and i have a extremly fast computer. Not even worth a illegal download in my opnion (i did pay $50 for it).

I ended up buying Trend Micro (http://www.trendmicro.com) for my comp. I ended up liking it so much i bought it for my other computer that i hardly even use! lol

Hi allyoop54,

First of all- welcome to TechTalk! :)

We ask that members not tag their questions on to a thread previously started by another member (regardless of how similar your problem might seem). Not only does it divert the focus of the thread away from the original poster's problem, but it also makes it less likely that you yourself will get the individual attention that you need.

Please start your own thread and post your question there. When you do, please try to give us as much specific info as possible regarding the problem (exact error messages, system specs, etc.).

For a full description of our posting guidelines and general rules of conduct, please see this page:

allyoop54,

I think your problem might fall into the "regardless of how similar your problem might seem" category that I mentioned in my last post.

In other words, in your case this might not be a question of infection by malicious programs. A Google search for the error you are getting returns at least one link which specifically relates the error message to an install of the autoshink program. Read the suggestion in the 4th post (by mrbass) in the following thread and also check out the link he posted there:

I tried everything with autoshrinkiso but nothing worked. An error 68 comes up when using autoshrinkiso.
I am also having problems when using DVDSHRINK3.1.7. Uusally when i would encrpt and encode a movie, it would automally start buring the movie to a DVD without using NERO. Now it seems as though i can't get either dvdshrink3.1.7 or nero to burn a dvd.
Please help! Before i forget. I went into START>RUN, TYPED IN REGSVR32 COMDLG32.OCX. It said I was registered. However, no better what was tried nothing worked.
