On a windows XP system, I try to download and install Windows Desktop Search 4.0 and it fails.

The error I get:

Windows Search 4.0 could not be installed on this system.

For more details, check the log file.

The contents of that file:

No idea how to resolve this. Any help is extremely appreciated!

Uninstall any previous version of WDS, if you can't uninstall via add/remove programs, run this file:


If this doesn't work either, delete the following registry keys:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows XP\SP3\KB917013"


... and try again.

That uninstaller does not exist, nor do those two registry keys :( – Ben Baril Feb 25 '10 at 17:53
That KB is for Windows Search V3.01, which I can't install either – Ben Baril Feb 25 '10 at 17:54
@Ben Baril - is your windows installer up to date?… – Molly7244 Feb 25 '10 at 18:45
Installed that, same story still. Any more information I can give you? – Ben Baril Feb 26 '10 at 23:03
@Ben Baril - i'm running out of ideas, except trying again on a clean XP installation ... or even better, use Everything instead of WDS :) – Molly7244 Feb 27 '10 at 2:03

Doing a bit of reading around your topic i have found this article which has been used by people getting similar errors as yourself, regarding WDS 3.1 albeit. This has seemed to fix the problem in most cases I have seen it mentioned.

Its these two lines that got me thinking it could be a registry error:
17.0.579: In Function TestVolatileFlag, line 12013, RegOpenKeyEx failed with error 0x2
18.0.579: In Function TestVolatileFlag, line 12045, RegOpenKeyEx failed with error 0x2

Worth a try, anyway. Let us know how it goes.

I'm not sure that this is your problem, but, I do know that "Windows Desktop Search 4.0" will only install on a 32-bit machine.

You have to install Windows Desktop Search 3.01 for Windows XP x64 Edition version on 64-bit computers.

Thank you for the text expansion. I get it. If microsoft ever breaks the link (which is likely), the information is still helpful. – HexaGamnon Mar 12 '13 at 14:27
