title: Winforms ClickOnce Installation Failing
body: <p>The Winforms application is created using VS2013 and is .Net 4.5.</p>
  <p>I have been developing it and installing upgardes on multiple machines for many years.</p>
  <p>However on my profile on my PC it now fails to install.</p>
  <p>The failure log file's main error message is...</p>
  <p>'COMPONENT STORE TRANSACTION FAILURE SUMMARY' then followed by a long list of files and the message...</p>
  <p>'- Staging of a component file (Sales\XYZ.rdlc) did not succeed.'
  OR
  '- Staging of a component file (EmailTemplates\ABC.htm) did not succeed.'</p>
  <p>I can solve the issue by uninstalling the previous version or running 'rundll32 dfshim CleanOnlineAppCache' and do a successfull installation but the same problem occurs when I install a new version later.</p>
  <p>I have done further testing by creating a new profile on my PC and successfully completed an initial ClickOnce installation and subsequently installed a new version successfully. So no problem here.</p>
  <p>So initially I thought the issue is probably something to do with my profile and not related to the actual install. However have since tried installing on one of my other PCs, where there was an existing install (and it had had new versions installed mamy times before) and it failed there as well.</p>
  <p>So very confused.</p>
