0x3 error using pdbstr (Source indexing) <p>I am trying to use the PDBSTR.EXE tool to merge version information into a PDB file and from time to time I encounter the following error: [result: error 0x3 opening K:\dev\main\bin\mypdbfile.pdb] &lt;- can be a different PDB file.</p> <p>An example of the command line that I use is: </p> <pre><code>pdbstr.exe -w -s:srcsrv -p:K:\dev\main\bin\mypdbfile.pdb -i:C:\Users\username\AppData\Local\Temp\tmp517B.stream </code></pre> <p>Could you tell me what would cause error code 0x3? </p> <p>If the error code is similar to the standard System error code 3 ERROR_PATH_NOT_FOUND, then it seems to think that the path K:\dev\main\bin\mypdbfile.pdb does NOT exist when in fact it DOES. However please note that my K: drive is a SUBST'ed drive.</p> <p>(System error code reference <a href="https://msdn.microsoft.com/en-ca/library/windows/desktop/ms681382(v=vs.85).aspx" rel="nofollow">https://msdn.microsoft.com/en-ca/library/windows/desktop/ms681382(v=vs.85).aspx</a>)</p> <p>Do you know what the 0x3 error code could possibly mean?</p>
