  <p>I know there are many questions of this nature, but none that I have found have fixed my issue.</p>
  
  <p>I installed R 3.6.1 and RStudio 1.2.1578 on a new Win 10 machine w/o admin rights.  Managed to get everything working except Rmarkdown.  My sessionInfo() is below.  If I open a command prompt, pandoc is findable:</p>
  
  <pre><code>C:\&gt;pandoc --version
  pandoc 2.7.3
  Compiled with pandoc-types 1.17.5.4, texmath 0.11.2.2, skylighting 0.8.1

  <p>I have pandoc installed at C:\Users\bosr\AppData\Local\Pandoc\</p>
  
  <p>I also tried @kevinushey's solution mentioned <a href="https://github.com/rstudio/rstudio/issues/3661" rel="noreferrer">here</a>
  which resulted in a second pandoc install at H:\rstudio-pandoc\</p>
  
  <p>Both pandoc installs are in my path (user) environment variable which I am allowed to set.</p>
  
  <p>I would be very grateful for any suggestions.</p>

  <p>Update: I had IT install pandoc using the admin password, and I am still getting the same error:</p>
