title: CHM compiles fine, but won't open
body: <p>I use a program that spits out HTML and hhp projects containing data from my databases.
  I then compile that hhp with Microsoft HTML Help Compiler (hhc.exe).</p>
  
  <p>It works well, but unfortunately for few projects, hhc compiles fine, but chm file is unusable.
  It reports "Cannot open the file: mk:@MSITStore‎: FileName"</p>
  
  <p>I have no problem with other chm files on my system. I have no problems with other chm I compile. If I remove several topics from my project produced file works again. It doesn't matter what topics I remove. Files that don't work are almost twice the size of files that work, even tho the html and project file is almost the same (very few changes), which leads me to think compression fails silently if size or structure of some file isn't right.</p>
  
  <p>Does anyone have experience like this and what could be the reason?
  For those that want to see example, this project will compile and work fine:</p>
  
  <p><a href="http://depositfiles.com/files/8thcqeiz7" rel="nofollow">Working chm project</a></p>
  
  <p>And this one compile but fail to open:</p>
