Run Time Error 48; Error in Loading DLL

Hi Phil and welcome to E-Learning Heroes!

Please follow the troubleshooting steps in this article to fix unexpected or erratic behavior in Articulate Studio '13.

Hi Leslie - thanks for providing the article. Unfortunately, it did not solve the problem. After going through the entire sequence, including the uninstall and reinstall of both Office and Articulate twice (lost the entire day) I am still getting the exact same error message, Run-time Error '48': Error in Loading DLL. I also had trouble when trying to insert an Engage .intr file into PowerPoint. It went unstable over an Active X issue. Any others suggestions?

Hi Phil!

Had you recently downloaded Update 3? Is that when the issue started?

Can you try the following to resolve the issue?

Install VSTO

Install at least .NET Framework 4.0

After installing the above, please restart your machine.

If this does not assist, I would recommend opening a ticket with support so that this can be looked into further.

I did both of these as part of the solution contained in the article you provided. I will open a ticket with support. Thanks!

Hi Phil,

We found that the issue is caused by having a registry key leftover after uninstalling Office 2013. To fix the issue, you'll need to delete the following registry key:

"HKEY_CLASSES_ROOT\TypeLib\{91493440-5A91-11CF-8700-00AA0060263B}\2.b"

By removing this key, Office properly falls back to the previous older version - 2.a - which is the correct installed version for PowerPoint 2010.

For reference, the entire incorrect key that is causing the problem is:

[HKEY_CLASSES_ROOT\TypeLib\{91493440-5A91-11CF-8700-00AA0060263B}\2.b\0\win32]

@="C:\\Program Files (x86)\\Microsoft Office\\Office15\\MSPPT.OLB"

Let us know if that resolves the issue. Make sure you have PowerPoint closed before making this change. We would also recommend backing up your registry or having your local IT group make this change.

As of a few days ago, I now get this precise error when trying to open the Record Narration window. This coincides with our recent Office upgrade from 2010 to 2013. Unfortunately the registry edit above did not fix the issue.

Hi Craig! 

Sorry to hear that you ran into difficulty with this. Did you try the repair option first listed in this article?

If that does not assist, you may need to work directly with our support team here so that we can check log files and see what's going on.

Went through the process outlined in the article. No luck. Will have to start a ticket.

Thanks for the update Craig. Sorry to hear that the repair did not assist you. I'd be happy to follow along with your case as well, just share the case number with me here.

Did full uninstall/clean/reinstall of Articulate and Office 2013 and problem appears solved. Thanks much.

Very good. Thanks for popping back in to share Craig.

For anyone else interested, sounds like Craig was able to follow this solution.

Actually - our support installed Office 2016 as opposed to 2013, so that may have been the difference that solved the problem.

Well, there is that then. Thanks for popping in to clarify and share :)

Hi, Eric -- Thanks for reaching out, and I see that you started a new thread on this topic over here, so I just wanted to stop in and share the link to that post for others who may be following along. I have created a Support Case for you, and I will share any relevant updates from your case so others may benefit, as well. Your patience is appreciated! 

Hi, 

I have the same error code coming up when I go to sync animations "Run Time Error 48; Error in Loading DLL". I have tried all the above steps and the error is still coming up when I go to sync animations. Where should I go from here? Thank you. 

Hello Karen,

Sorry to hear that you've run into a similar issue. We haven't seen this one crop up in a while as this thread is a bit dated.

You mention going through all of the above steps. Did you conduct the uninstall/reinstall as outlined here?

I glanced through this thread and the related support cases and that seems to be taking care of the issue.

If you need further assistance and/or the uninstall/reinstall does not alleviate the issue for you, please reach out to our support engineers here.

Thank you, yes I have tried that....so I will submit a case to support. 

Thanks Karen! You should be hearing from someone soon.
