When I get an e-mail with an attach picture, I double click on the attachment and get the following error message "This application has failed to start because UXCore.dll was not found. Re-installing the application may fix the problem." Then I click OK and get "Error loading C:\Program Files\Windows Live\Photo Gallery\WLX Photo Viewer.dll The specified module could not be found."

If I save the attachment to a file, say a temp file, and then try to open it, it does open just fine. How do I get back to where I can open an attachment right at the e-mail source? Thanks in advance for any help you can give me.

Brief summary and targeted fixes for the “UXCore.dll not found” / “WLX Photo Viewer.dll” error (seen when double‑clicking Outlook attachments).

UXCore.dll is a component used by the Windows Live / Photo Gallery family (the same shared UX modules are used by Photo Gallery and Movie Maker), so the error usually means a Windows Live component or its dependencies are missing, mismatched, or the viewer entry Outlook is calling points at a broken install. (learn.microsoft.com)

Practical, safe order of work (try these in sequence):

  • Prefer repair/reinstall of Photo Gallery (or Windows Essentials) rather than downloading individual DLLs from random sites — Microsoft explicitly warns about unsanctioned installers and discontinued Essentials builds. (support.microsoft.com)
  • Repair Windows system files first: run the image-repair command and then the system-file check from an elevated prompt (for example run the DISM restore command, then run the System File Checker scan). This fixes corrupted or missing protected files that can cause DLL errors. (support.microsoft.com)

If reinstall/repair doesn’t fix it:

  • Use Process Monitor (Procmon) to trace where the viewer is trying to load UXCore.dll and which folder or registry path is failing; that tells you whether Outlook is calling a stale viewer DLL or looking in the wrong folder. If a program is trying to load dependencies from the application folder, copying the matching (same-version, same‑bitness) files from the Windows Live “Shared” folder into that app folder has been used as a last‑resort workaround. Use Procmon first to confirm. (learn.microsoft.com)

Other important notes:

  • ’s final discovery (two Photo Gallery entries in “Open with” and one being broken) is a common cause — an invalid association can cause the attachment-open path to hit a broken module even though the saved-file path works. Reset the default program for JPEGs or remove the stale Open With entry.
  • On 64‑bit Windows be careful where you place DLLs (System32 vs SysWOW64) and always match bitness; Windows’ folder names are counterintuitive so verify before copying. (howtogeek.com)

Acknowledgements: ’s reinstall suggestion, /’s DLL-download idea (use caution), and ’s SFC hint all point to the right troubleshooting directions; the above orders them to reduce risk and improve diagnostic value.

Or if the above not helps,then you can try the direct download

Member Avatar for murpeg

The download from caperjack's URL when well but did not fix the problem. It is still the same error message I get.

FlamingClaw's down load resulted in this message "Photo Galllery can't open this photo or vidio. This file formate is not supported, or you don't have the latest updates to photo Gallery."

Thanks for trying but what do I try next?

you are not suppose to try and open that download ,you are to copy it to your system32 folder , usually found here ,
C:\WINDOWS\system32

Member Avatar for murpeg

caperjack - good to hear back from you. When you said "you are to COPY it to your system32 folder" did you mean for me to SAVE it to my system 32 folder or did you mean for me to save it to a temp file and then copy and paste it into syatem32 folder or what? I think we may have a solution to this problem if SAVE is what you want me to try. When I looked in system 32 folder there was NO UXCore.dll
I await you reply. Thanks.

I really would like to hear back from some one if I am correct to SAVE (not copy) to systems32 folder because before I do it, I want to know it is the right thing to do as I know this systems32 folder is a very sensitive folder. Thanks for any help you can give me.

save to system32 is good ,

Member Avatar for murpeg

Save to system32 did not cure the problem and saving to c:\program files\windows live\installer also did not work.

If I send and attached picture (jpg) to my other mailer - hotmail rather then outlook- the attachment will open just fine.

I don't use Live anything ,don't like it , so i open my attached picture with my default choice of windows picture and fax viewer !,maybe you need to change the default viewer to get it to work in outlook

Member Avatar for murpeg

To change my default viewer to "Windows Picture and Fax Viewer in Outlook is a good idea, but what is the path to do that. I can not find it. Help please.

Member Avatar for murpeg

I want to thank you so much for your continuing effort to help me. I however want to help back. My problem is solved by your suggestion to change the viewer back to Windows viewer and fax. I found a way to change back to windows viewer as my default viewer. Go to and change JPE, JPEG and JPG to windows and fax viewer. It works. Yeh - ho finally got this problem solved and I hope this info will help others.

The UXCore.dll problem is not solved, I have just went around it. That works for me. Any one who knows how to solve the "UXCore.dll can't find" problem, please reply.

If its a missing or corrupt system DLL, have you tried running SFC?

sfc /scannow

Member Avatar for caperjack

when doing a google search, you seem to be the only one with this problem!, must be a conflict with something else on your computer !
are you using outlook or outlook express,if outlook what version

Member Avatar for murpeg

Outlook 2003
Last night I told you that I changed my default viewer from Gallery to Windows Picture and Fax viewer. Today I was looking at some pictures and noticed that my zoom in was not as smooth and I could no longer grab the picture to move it around like I could when using Gallery. So I’d like to go back to Gallery as default but don’t want that UXCore.dll problem back when trying to open a mail attachment. Believe it or not - I got it. How? Well I noticed that there were two Gallery viewers in where you choose the viewer you want to open with. So I thought maybe one of them is good and the other one has the .dll problem. Bingo – bang go, that is exactly what I fond the case to be. You got to get lucky once in awhile. I guess that I got a corrupted download one time or something, but it is all working now. Any thoughts? So thanks again and mark this as solved.
