"Class Not Registered"

Using VB6 with SP3.  A large application.  This morning I came to work, launched my project.vbp, and got four "Class Not Registered" errors, like:

Looking for object with CLSID: {0002E005-0000-0000-C000-000000000046}-- Continue loading project?

I proceeded through the errors, during which four error logs were generated, like:

Line 42: Class Threed.SSPanel of control pacifier was not a loaded control class.

WHAT HAPPENED?  This is scary.  What do I do?  Please help. -- Norm

try starting a new .exe project and going to project -> components and try adding some control to your project.  see if it generates an error there as well. if it does, see this article (you may want to see it anyways for any possible future reference)

Welcome to DLL Hell.. <sigh>.

Sounds like someone ran an UnInstall on your computer.. and at the No references exist for this DLL, do you want to delete it.. answered Yes.

-OR-

A program was installed that overlaid the current version of threed that you were using.

-OR-

threed somehow got moved from the location where it was expected.

-OR-

a Registry cleaning program deleted a reference.

-OR-

it was gremlins.. LOL.

AzraSound: Thank you for your reply.  I followed the instructions in the article you referenced.  First I started a new VB application, and sure enough, I got the error described in the article.  And when I opened the Component Dialog, no components were displayed.

Next, I checked that ComCat.DLL indeed exists in C:\WINNT\system32
 
Continuing: Following the article, I typed the following in the RUN dialog:
RegSvr32.Exe C:\WINNT\system32 > \ComCat.DLL

(I'm not sure about the spaces surrounding ">")

I got:
LoadLibrary ("C:\WINNT\system32") failed. GetLastError returns 0x0000007e

What now please? -- Norm

The correct RegSvr32 command is:
RegSvr32.Exe C:\WINNT\system32\ComCat.DLL.

Although I think you should perhaps look at re-installing both VB6 and SP3!
This would be the safest route to take!

you do not need the ">"

just

RegSvr32.Exe C:\WINNT\system32\ComCat.DLL

Thanks to all.  Should be a way to distribute the points.

AzraSound: The Microsoft article you referred me to had a ">" in the instruction!  As soon as I followed your last remark, it worked.  I had one more thing I apparently had to register "by hand", then all was well.

This whole thing started like this: I inherited this computer from an ex-employee, and about once a month I get a message "Update is scheduled to run now, Yes/No".  I always said "No". This morning I said Yes, and spend the rest of the day repenting in sorrow.  I sent e-mail to the guy, asking what that thing is, and how to get rid of it.

Thanks again -- Norm
