      IE 11 copy/paste problem

      It has come to our attention that people using Internet Explorer 11 (IE 11) are having trouble with copy/paste to the forum. If you encounter this problem, using a different browser like Firefox or Chrome seems to get around the problem. We do not know what the problem is, but it seems to be specific to IE 11 and we are hopeful that Microsoft will eventually fix it.

Shell.dll missing

11 posts in this topic

I finally got rid of Home Search, using a combination of CWShreader, Spybot, Ad-aware, TrojanHunter, Registry mechanic, and PCBug Doctor.


I have one remaining problem after all the 'fixing.'


I use a rolodex program called Sharkware. When I start it I get an error message which says: Cannot find SHELL.DLL


Following is an excerpt from CEShredder scan only report:

Hosts file not present

Shell Registry value: HKLM\..\WinLogon [shell] Explorer.exe


I've reinstalled Sharkware, but to no avail. same error message.


I've downloaded a new shell.dll, and replaced the old one. still same message.


so, How can I put that registry value back?

Thanks in advance. Jashac

I'm sorry, but we need some additional information beore we can help. For example, which version of Windows are you running? version of Internet Explorer? Patch level?


I realize that you have already cleaned up your system, and I congratulate you. However, I would still recommend posting a HijackThis log, as it will contain information (such as I mentioned above) that will help resolve your issue.


Download 'Hijack This!'. http://www.spywareinfo.com/~merijn/files/HijackThis.exe

Save it in a convenient permanent folder such as C:\HJT\, double click HijackThis.exe, and hit "Scan".


When the scan is finished, the "Scan" button will change into a "Save Log" button.

Press that, save the log, Ctrl-A to Select All, and copy its contents here. I don't believe that there will be anything to fix, so just post the log and we'll try and help!

As I mentioned it's the Shell.dll missing entry (I think) which seems to be causing the problem.

Also missing mhgcal.vbx.


Any ideas as to how to restore what is needed?

I'm looking over your log and doing some research on the vbx file. I'll be back with you on this shortly!

Used to display and select dates from a monthly calendar.

You can display and select multiple dates, display a 3-D

appearance around the edge of the control as well as the current

selected date, control colors, display an image in the background

or at the top of the control, and support multiple languages.


Download here:



(*48.7K 04-Jun-1996 )

That's an App specific file. Not Windows file.

I'm Not sure about the version or location.


As for shell.dll, it's known and caused by one cws trojan.

Search for it in:

-System32 folder

-System folder

-System32\dllcache folder.


If it's reported missing it's probably missing from System32.

Replace it by copying it from one of the other locations (it should exist in all 3)


Good luck :D

The shell.dll was missing from system32. When I replaced it that error dissappeared.



I've messed with the MGHCAL.VBX. It exists in Windows/system and Windows/system32. I downloaded another version and tried it.


I reinstalled Sharkware (the application I'm having trouble with)


I still get the error message:

Can't load Custom Control DLL: C:\windows\system\MHGCAL.VBX


It's there, and I've substituted an older version, and replaced it then with the newer version. No luck


Thanks a bunch for helping with the Shell.dll.

Any ideas about the MHGCAL

Thanks again, jashac

did you delete (or rename) the existing mhgcal.vbx before reinstalling Sharkware? The installer may have not overwritten the file if it was present on the system.

I renamed the file before copying the downloaded version into the folder.


and then tried it


I've tried with both the old and new.


The thing that's bugging me is that it was working before the Hijack. So if the .vbx file is there, why won't it load? An older version (the one I downloaded) ought to be even better, given that the application (Sharkware) is a Windows 98 version program.


I'm really at a loss.

Even more wierd...


I loaded the problem program (Sharkware) on my home computer which runs Windows XP (not pro).

It runs fine.

I copied all the VBX files and transplanted them to my work system. I still get the same error message.

One more thought, brought up by one of the Moderators: have you completely removed Sharkware from your system (down to backing up the data files and uninstalling/deleting all files and folders, including the VBX files) and then reinstalling? That's about the last thing I can come up with. Please let me know if you have tried that, and if not, can you try it and let me know if it made a difference?

Thanks for the thought.


Sharkware does not show up on the Add or Remove Programs list. And it does not have it's own uninistall.


I have deleted all the files I can find, but the install program still thinks Sharkware is still installed, and provides the option to update, or reinstall. I chose reinstall.


I think if I could really do a fresh install that would solve the problem, but I haven't figured out how to totally rid the system of all remnants.


This is really a hassel, but I have all my contacts, and history, an notes in this data base.


thanks again for your help and suggestions.
