Hi,

I've purchased & downloaded RC4 today, the installation appeared to go smoothly, and I have registered, entered the key and switched off.

When I now try to start RC4, I get the following error message:

 

Component 'COMDLG32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid

 

If I change its properties to NOT run as administrator, it fires up ok.

But I am trying to 'run as administrator' simply because I run FSX & all addons this way & I wanted to avoid any problem.

 

Does anyone know why I would get this error message?

Is it not possible to run this program as administrator?

In any case, should it run fine without running as administrator?

 

Many thanks

Keith

Hello!

 

I had the same problem the other day when I tried to install Radar Contact.  You need to go to Microsoft and download/install the Visual Basic 6.0 Runtime.  COMDLG32.OCX is a Visual Basic file that needs to be installed before Radar Contact will work properly. 

 

Hope this helps!

That's a great help and a very quick response thanks Trent, downloading it now

I remember having to download some alternate files after I installed RC4 and tried to get it to run, and now all is well.  As I look just now, I don't even run RC4 in administrator mode and I've never had any issues with it.

Installing VBRun 6 has not helped for me. But thanks anyway Trent, and thanks E6BAV8R, I will do likewise as it seems to be happy to run outside admin mode.

I remember having this issue aswell. There is a fix, I'm sure, on the radar contact website. It helped for me.

I did follow one suggestion on the site using regsvr32 command, but it did not work for me. I'll take another look though thanks

You can get the .ocx files from here: http://www.ocxdump.com/ (I, for myself, did.) and then copy them either to

Windows\System32 (32 bit)

or

Windows\SysWoW64 (64 bit)

 

Then open a command window (easiest: shift+right-click into a folder, then select "open command window here") and enter:

regsvr32 c:\windows\system32\[NAME OF THE OCXFILE] (32bit)

or

regsvr32 c:\windows\syswow64\[NAME OF THE OCXFILE] (64bit)

 

Normally, you should get a message about the file having been registered successfully.

 

Do this until RC4 starts and runs without errors.

 

 

 

 

 

- Edit:

 

Or download my backup collection of dll and ocx files for RC4 from here:

http://www.mediafire.com/?y8dgh8417k3i6wf

 

Unzip; copy the files in the "Windows" folder into your "Windows" folder; if your Windows folder is *not* on drive C:\, edit the path to your windows folder in the .bat file (can be done with notepad); and finally run the bat file. That should do it.

Thanks Bjoern, that's very helpful. I will download them and put them in my RC4 backup folder for safe keeping.

 

And success, I finally got it working as administrator, by:

1) running CMD as administrator,

2) then UNregistering the ocx file (regsvr32 /u comdlg32.ocx)

3) then re-registering it (regsvr32 comdlg32.ocx)

 

RC4 then started as admin.

 

This post also helped a lot:

Bit annoying that it's necessary to search and find these elusive missing bits of the jigsaw, but I do understand that most of FSX and it's extras were created before Win 7 came along

 

Thanks to all for the help, finally going to give it a go
