Missing MSXML4

[woodart]

I have suddenly developed a rash of applications failing to launch due to a "Missing MSXML4" file. A file search verified that it is present in the "Sys/WOW64" folder so I presume that it is somehow corrupted.

What is the best way to repair or replace this?

Hi woodart try here Download: MSXML 4.0 Service Pack 3 (Microsoft XML Core Services) - Microsoft Download Center - Download Details or run the system file checker sfc /scannow command and see if it finds and replaces the corrupt file

You may need to run the command 3 times if any corrupted files are found.

I have the scan running right now. I tried the 4.0 SP3 download but it didn't fix it.

Hi woodart ,It may be wise to also run an A/V scan using mbytes or similar scanner just to be on the safe side

Good idea...

Microsoft Security Essentials is a good free AV program.

 

[woodart]

Well, I have run the sfc /scannow 3x, with no errors showing, done an AV scan with no infections and uninstalled/reinstalled MSXML4 SP3 with no positive result. I have also reinstalled the affected programs.

I can't imagine what's keeping the programs from seeing it.

Yep. I was hoping to avoid it but I think you're right

The Windows Updates may need to be checked and reinstalled, with any themes and sounds being set back to their defaults, however your data and programs will remain the same.

Keep us posted.

Will do it tonight.

There are 2 msxml4 dlls in SysWOW64. msxml4.dll , and msxml4r.dll. You might try replacing them with these from my system. You might also try registering both

Start> In search box type cmd> Enter> Right click on cmd.exe in results above and choose run as administrator> When advanced command prompt opens type

CD C:\Windows\SysWOW64

Enter

Now type

regsvr32 msxml4.dll

Enter

You should get a success message

Now type

regsvr32 msxml4r.dll

Enter

You should get a success message

You may need to reboot to allow changes. Good luck. A Guy

Sorry for my absence on this thread but my system developed some other issues that have had me distracted.

Iran all the scans with no success and then tried a system restore to a point before the problem surfaced. The restore failed on several restore points so I tried a repair from the Windows 7 disk and it failed to complete as well.

I finally tried to do an upgrade re-installation and it stopped and gave the message that my Windows installation was more current than the the version I was trying to install and thus could not complete.

In the meantime, yesterday I booted up only to find that it wouldn't take any mouse inputs and while I tracked that down (apparently a dead mouse), I noticed that my volume was muted. When I opened the mixer, I saw the sliders all move to the bottom on their own and when I moved them, they all immediately began a leisurely trip back to the bottom. When I began trying to sort that, I saw a box pop up telling me that my onboard SoundMAX device had uninstalled itself and when I reinstalled the software, it gave me an error message saying that no supported device was found, even though it shows up in the device manager but not in the control panel's sound device list.

All of the sound issues cropped up when I installed a new GTX670 a few days back and it apparently disabled my SoundBlaster X-Fi card. I've found that it's onboard HDMI sound messes with BIOS and older boards (mine is about 4 y/o) don't play nice with two PCI-E sound devices.

Anyway, I'm on the verge of doing a full Windows reinstall but if anyone has any ideas on soling any of these issues, I'm all ears!

I replaced my .dll's with yours and tried to register them through the command prompt but got the message "Failed to load- Missing module" on both.

If your going to do a clean install then choose one of the tutorials which applies to your system the most:

• http://www.sevenforums.com/tutorials/219487-clean-reinstall-factory-oem-windows-7-a.html - Windows Pre-Installed
• http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html - Windows Installed Manually

You will want to download and save your Ethernet driver to a USB drive or a different computer, so you are able to connect to the Internet right after the installation.

Generally when problems start to crop up one after another, a clean install is in order I'd suggest you get a 2nd hard drive, either internal or external, and a good backup program and make system images regularly. 15-20 minutes tops and you are back to the last good image. I can personally suggest Acronis True Image. Many here like the free Macrium Reflect. Full system images are a great peace of mind, and can be a huge time saver. A Guy

 

[woodart]

Actually, I have 6 internal/eternal drives worth 6.5TB so I'm probably in pretty far shape there but the system imaging software sounds like a real time saver.
