Error Message - 0xC004D401<p>I had this error appear today after updating my iTunes and restarting. I've followed the steps indicated in other posts (Diagnostic report included at end of message), and the Reliability Monitor indicated that the only application installs I've had were Microsoft WSE 3.0 Runtime on 06/06, and NVIDIA Control Panel on 31/05. The iTunes/Safari/Bonjour update is the only one I've done today. I don't know whether it's related/relevant or not, but I have also lost access to altering user groups privileges in Internet Explorer, as well as the User Groups in Explorer. I've also lost access to my Restore functions, and every restore point I had previously created has been deleted, leaving me unable to create another. I would have considered just reinstalling Vista, except it came with the PC and I don't have any discs. I tried to request email help but when I try and access the page, it constantly freezes on the loading bar. When I ran the validation diagnostic tool on the MS website, it failed several ActiveX tests. <br/><br/>I'm not sure what I should do now, thanks in advance for help.<br/><br/>---<br/><br/>Diagnostic Report (1.9.0006.1):<br/>-----------------------------------------<br/>WGA Data--&gt;<br/>Validation Status: Invalid License<br/>Validation Code: 50<br/>Online Validation Code: 0xc004d401<br/>Cached Validation Code: N/A, hr = 0xc004d401<br/>Windows Product Key: *****-*****-27HYQ-XTKW2-WQD8Q<br/>Windows Product Key Hash: U8YEZzymoD4DMyaMb32rPrNIS90=<br/>Windows Product ID: 89578-OEM-7332157-00061<br/>Windows Product ID Type: 2<br/>Windows License Type: OEM SLP<br/>Windows OS version: 6.0.6001.2.00010300.1.0.003<br/>ID: {A612C7C1-E3D0-41FA-92EB-B18DD15DBADA}(3)<br/>Is Admin: Yes<br/>TestCab: 0x0<br/>WGA Version: Registered, 1.7.69.2<br/>Signed By: Microsoft<br/>Product Name: Windows Vista (TM) Home Premium<br/>Architecture: 0x00000000<br/>Build lab: 6001.vistasp1_gdr.080917-1612<br/>TTS Error: M:20090630190001908-<br/>Validation Diagnostic: <br/>Resolution Status: N/A</p> <p>WgaER Data--&gt;<br/>ThreatID(s): N/A, hr = 0x80070002<br/>Version: 6.0.6002.16398</p> <p>WGA Notifications Data--&gt;<br/>Cached Result: N/A, hr = 0x80070002<br/>File Exists: No<br/>Version: N/A, hr = 0x80070002<br/>WgaTray.exe Signed By: N/A, hr = 0x80070002<br/>WgaLogon.dll Signed By: N/A, hr = 0x80070002</p> <p>OGA Notifications Data--&gt;<br/>Cached Result: N/A, hr = 0x80070002<br/>Version: N/A, hr = 0x80070002<br/>WGATray.exe Signed By: N/A, hr = 0x80070002<br/>OGAAddin.dll Signed By: N/A, hr = 0x80070002</p> <p>OGA Data--&gt;<br/>Office Status: 109 N/A<br/>OGA Version: N/A, 0x80070002<br/>Signed By: N/A, hr = 0x80070002<br/>Office Diagnostics: 77F760FE-153-80070002_7E90FEE8-175-80070002_025D1FF3-364-80041010_025D1FF3-229-80041010_025D1FF3-230-1_025D1FF3-517-80040154_025D1FF3-237-80040154_025D1FF3-238-2_025D1FF3-244-80070002_025D1FF3-258-3</p> <p>Browser Data--&gt;<br/>Proxy settings: N/A<br/>User Agent: Mozilla/4.0 (compatible;

This can be caused by a malicious program (spyware, malware, virus) or by manual file modification (by a user of the system). There is also a very small chance that an Update may fail in mid-update and cause this type of issue. As a safety mechanism, Updates are made so that if they fail, they roll back any updating that was done before the failure, but there is an off-chance that the roll back did not occur. </span></p> <p class=MsoListParagraphCxSpMiddle style="margin:0in 0in 0pt 0.5in"><span style="font-family:Arial;font-size:small"> </span></p> <p class=MsoListParagraphCxSpLast style="text-indent:-0.25in;margin:0in 0in 10pt 0.5in"><span style=""><span style=""><span style="font-family:Arial;font-size:small">2)</span><span style="font:7pt &quot;Times New Roman&quot;">    </span></span></span><span style="font-family:Arial;font-size:small">A critical system file was modified <span style="text-decoration:underline">In Memory</span> - What this means is the file itself (on the hard drive) is un-modified, but the code, from that file, running in the system, was modified in some way and is caused by a running program that is incompatible with Vista.</span></p> <p class=MsoNormal style="margin:0in 0in 10pt"><span style="font-family:Arial;font-size:small"> </span></p> <p class=MsoNormal style="margin:0in 0in 10pt"><span style="font-size:small"><span style="font-family:Arial"><span style="">  </span>Because there is No Mismatched files listed under the &quot;File Scan Data--&gt;&quot; line of your Diagnostic Report, we know that your issue is an <span style="text-decoration:underline">In Memory</span> Mod-Auth and therefore caused by an incompatible program. This means there is a program install and Running that is trying to access parts of the OS that Vista does not allow, which by definition, means it is incompatible with Vista. </span></span></p> <p class=MsoNormal style="margin:0in 0in 10pt"><span style="font-family:Arial;font-size:small">NOTE: We have seen an increase in this type of issue and we believe it is unlikely that software writers are still making programs that are incompatible with Vista.

But to my disappointment, when i tried to &quot;learn more online&quot;, i can't get connected. It's not just that, my PC is black and blank without any access to any programs,files, and the windows itself. Just a black background with that window's software protection's warning (even when i ran with a Safe Mode). Most of the solution to troubleshoot the problem requires an internet access or even a simple step of clicking the Windows Start button which i'm unable to do with the state my PC is in.<br/> Thanks in advanced for your help.<br/>Sat, 05 Sep 2009 14:16:57 Z2009-09-05T14:16:57Z
