Greetings all! Here's my problem, and apparently alot of other people's as well judging by the massive forum entries worldwide. After installing service pack2 for Xp Home, the Search Companion no longer functions and causes the error "Some files needed are missing, you may need to run setup". Nothing fixes this problem. Microsoft's solution is only offered for sp1. Not only have I lost the ability to search for files and folders on my computer, the search function in Internet Explorer causes the same error, and I no longer have the option of customizing and choosing different search engines for IE.

What's up with that?

I have the same problem....If you have a solution for this ...please let me know..I have been all over the internet looking for a soluton and I found persons with the same problem with no answers...

OR:

OR:
Start-Run:
regsvr32 /i "C:\Windows\Srchasst\srchui.dll"
regsvr32 /i "C:\Windows\system32\urlmon.dll"
regsvr32 "C:\Windows\system32\jscript.dll"

After many months of searching, the solution, or at least one that works for me was found in another forum.

Since installing WinXp service pack 2, I received the error message indicating files were missing required to load the search companion (dog). This prevented the search interface from loading.

This is a screenshot illustrating my problem. My desktop is showing through where the search fields should be.


To revert the search interface to an earlier version (without the animated companion icon), add a new key to the registry. The search interface will then load and appear as it did in prior versions of Windows. Who needs the animated companion icon anyway, right?


Open the registry editor by going to: Start>Run and type regedit and click OK. AS ALWAYS, YOU SHOULD MAKE A BACKUP OF THE REGISTRY BEFORE MAKING ANY CHANGES. For instruction on backing up the registry, go to http://support.microsoft.com/kb/322756#2

Then Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\CabinetState folder.

Go to: Edit>New>String Value.

Right-click the newly created key and rename it to "use search asst" without quotation marks. Click OK.

Double-click the new "use search asst" key and type "no" in the Value data field. Do not use quotation marks.

Close the registry editor.

This is a screenshot showing the subkey named "use search asst" and its value of "no".


Now when you go to: Start>Search the search interface should load and look like the one shown below.



I hope this helps those of you that have lost the ability to search files and folders on your computer after installing WinXp service pack 2.

After days of searching and trying this solved the problem for me:

regsvr32 C:\Windows\system32\msxml3.dll

This did it for me - thanks! And without having to install 'Windows Genuine B.S.' via Microsoft - dodge software! Strangely my genuine XP disc is not recognised as such by the system, probably as it's OEM/with a PC only :-(

BTW with that nasty Virtumonde virus hitting the Search Assistant you'll probably get more of these queries.
