    text
    copied!<p>We deploy our application using ClickOnce, installed from a file path. For 24 versions it has been working perfectly - now, on version 25 I get the following error once the application has installed and it launches:</p> <p><a href="http://i49.tinypic.com/zk4krl.png">alt text http://i49.tinypic.com/zk4krl.png</a></p> <p>If I test a previous deployment on the same machine, it works.</p> <p>Where can I even begin to look to find the cause of this error? I already checked the windows event logs - nothing.</p> <p><strong>EDIT:</strong> I noticed that while the dialog is displayed, a temporary xml file 'WER561D.tmp.WERInternalMetadata.xml' is generated in my temp folder. Here is the contents (it might contain clues helpful to those more knowledgeable in this area than I):</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-16"?&gt; &lt;WERReportMetadata&gt; &lt;OSVersionInformation&gt; &lt;WindowsNTVersion&gt;6.1&lt;/WindowsNTVersion&gt; &lt;Build&gt;7600 &lt;/Build&gt; &lt;Product&gt;(0x4): Windows 7 Enterprise&lt;/Product&gt; &lt;Edition&gt;Enterprise&lt;/Edition&gt; &lt;BuildString&gt;7600.16385.x86fre.win7_rtm.090713-1255&lt;/BuildString&gt; &lt;Revision&gt;1&lt;/Revision&gt; &lt;Flavor&gt;Multiprocessor Free&lt;/Flavor&gt; &lt;Architecture&gt;X86&lt;/Architecture&gt; &lt;LCID&gt;1033&lt;/LCID&gt; &lt;/OSVersionInformation&gt; &lt;ProblemSignatures&gt; &lt;EventType&gt;CLR20r3&lt;/EventType&gt; &lt;Parameter0&gt;applaunch.exe&lt;/Parameter0&gt; &lt;Parameter1&gt;2.0.50727.4927&lt;/Parameter1&gt; &lt;Parameter2&gt;4a275abe&lt;/Parameter2&gt; &lt;Parameter3&gt;mscorlib&lt;/Parameter3&gt; &lt;Parameter4&gt;2.0.0.0&lt;/Parameter4&gt; &lt;Parameter5&gt;4a275af7&lt;/Parameter5&gt; &lt;Parameter6&gt;4f3&lt;/Parameter6&gt; &lt;Parameter7&gt;0&lt;/Parameter7&gt; &lt;Parameter8&gt;System.Security.Security&lt;/Parameter8&gt; &lt;/ProblemSignatures&gt; &lt;DynamicSignatures&gt; &lt;Parameter1&gt;6.1.7600.2.0.0.256.4&lt;/Parameter1&gt; &lt;Parameter2&gt;1033&lt;/Parameter2&gt; &lt;/DynamicSignatures&gt; &lt;SystemInformation&gt; -- removed for privacy reasons -- &lt;/SystemInformation&gt; &lt;/WERReportMetadata&gt; </code></pre> <p>Another key point is that I am publishing via Visual Studio, there is no manual manifest editing going on.</p>
