title: Crystal Reports for Visual Studio installation error 1904
body: <p>Somehow my long-time running install of CR for Visual Studio 2013 Professional stopped working. I could not open any .rpt files.  I tried in VS2017 and VS2010...same thing.  So...</p>
  
  <p>Trying to install/update to the latest Crystal Reports for VS 13-0-23.exe, downloaded from the SAP website.  Running as Administrator, I get errors 1904, which seems to be issues with Framework 4.0. </p>
  
  <pre><code>Error 1904. Module C:\Program Files (x86)\SAP BusinessObjects\Crystal Report for .NetFramework4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\craxddrt.dll failed to register. Result -2147023898. Contact yourself!
  </code></pre>
  
  <p>Progress update Monday: I seemed to have been able to reinstall Framework 4.0. Then, Installing CR again, I pressed "Ignore" on each of the 6 failed to register errors.</p>
  
  <p>Then, trying to manually register these dlls using RegSvr32, I get errors:</p>
  
  <pre><code>The moddule 'craxddrt.dll' failed to load.
  Make sure the binary is stored at the specified path or debug
  it to check for problems with the binary or dependent .DLL files.  
  Invalid access to memory location.
  </code></pre>
  
  <p>and VLE.dll register complained:
      The module 'vle' may not be compatible with the version of Windows that you are running.</p>
  
  <p>I'm running Windows 7 Professional, so???</p>
