RdrCEF.exe Bad Image

[brianh20631124]

I am using:

Windows 7 Home Premium Version 6.1 (Build 7601: SP1) 64bit.

Acrobat Reader DC, up-to-date (Version 2017.012.20098).

I always keep my software up-to-date so I don't think this is a source of the problem - unless you know different!

When I open a pdf document, I am getting the error message -
   RdrCEF.exe - Bad Image
   c:\windows\system32\credssp.dll is either not designed to run on Windows or it contains an error.

I have tried un-installing the application, cleaning the Registry (with Piriform's Ccleaner) and re-installing Reader but this does not clear the problem.

This does not appear to cause any problems with reading the document but there is always a suspicion that I am missing something and it is annoying.

Any help would be appreciated.

Hi Brianh,

As per the description above, you are getting an error message RdrCEF.exe Bad Image when you open a PDF file in Adobe Reader DC, Is that correct?

You may uninstall Reader DC using this cleaner tool: Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs

Restart your machine and download the installer using this link: Adobe - Adobe Acrobat Reader DC Distribution

Try installing again and check if that helps. Let us know how it works for you.

Hello Anand,

Replying to your e-mail bounces back with the message begining -

"This is the mail system at host mx1-in2.phx1.jivehosted.com.

I'm sorry to have to inform you that your message could not

be delivered to one or more recipients. It's attached below.

Anyway, the answer to your first question is, Yes!

Please note that Reader has always worked OK for me in the past, even since this 'problem' has arisen so it's more an annoyance than a real problem.  I would add that the error message came up even if I simply opened Reader without asking it to open a document.  And once it has been dismissed, it won't come up again until I have shut down my PC and re-started it.

Anyway, I have done as you bid.  Along the way, as suggested on the Distribution page, I checked my PC's configuration and I note that I do not have the requisite 1GB RAM, only 4096MB, so I wonder if this is crucial.

At this point, the error message still arises exactly as before.

I've al.so read the item in the link which you provided.  My situation is similar but it is a different dll: are you suggesting that I could safely try a similar procedure with my dll?

Thank you and best regards,
Brian Hammond

Hi Brianh,

Sorry for delayed response. 1GB is equivalent to 1024 MB of memory, so you have enough memory space i.e. 4096MB = 4GB.

* Note: Please make sure you take a backup of the registry before editing any value of DLL.

Hope this helps, and keep us posted with the results.

Hello Anand,

Yes, of course I knew that 1,000MB = 1GB.  I was obviously having a bad day!

Anyway, thanks for all your help but, having installed the latest Windows updates, the problem seems to have gone away. I'll keep my eye open in case it returns, of course, in which case I'll be back here for more advice.

Many thanks,
best regards,
