title: (IIS8.5)Microsoft Excel cannot open or save any more documents
body: <p><strong>Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space. • To make more memory available, close workbooks or programs you no longer need. • To free disk space, delete files you no longer need from the disk you are saving to.</strong></p>
  
  <p>I am getting this error while opening an excel sheet in my application
  Application is running fine on <code>IIS5</code> and <code>IIS7</code> but when I shifted it to <code>Windows server 2012 R2</code> with <code>IIS8.5</code>  it didn't worked
  I googled and found some solution but they also didn't worked.</p>
  
  <p><strong>Here is what I have tried</strong></p>
  
  <pre><code>For both 32-bit and 64-bit versions of Windows, the folder “C:\Windows\System32\config
  \systemprofile\desktop” must exist and you need Full Control permissions to the 
  “systemprofile” and “desktop” directories.
  
  
  
  For 64-bit versions of Windows 7 or Server 2008 and higher, the “C:\Windows\SysWOW64
  \config\systemprofile\desktop” folder must also exist and you need Full Control
  permissions to the “systemprofile” and “desktop” directories.
  
  
  
  For 64-bit versions of Windows Vista, the “C:\Windows\SysWOW \config\systemprofile
  \desktop” folder must also exist and you need Full Control permissions to the
   “systemprofile” and “desktop” directories.
  
  
  
  For Windows 8.1, in addition to the above, the Windows Registry Key
   [HKEY_Current_User\Softwware\Microsoft\Windows\CurrentVersion\Explorer\User Shell
   Folders\Cache] must be set to C:\Windows\Temp
  </code></pre>
