When I try and load the openCpu library in Rstudio and RGui on Windows server 2008 R2, SP1 I get the message:

"The program can't start because MSVCR90.dll is missing from your computer. Try reinstalling the program to fix this problem."

The script then gives the following messages in console:

"Intiating OpenCPU server ... Using config: C:/users/[username]/documents/.opencpu.conf Waiting for server to respond... Server unresponsive; restarting. OpenCPU stopped. Using config: C:/users/[username]/documents/.opencpu.conf"

It will keep repeating this until force stopped. The server, however, is running.

I am sure that MSVCR90.dll is neither missing nor damaged. I have uninstalled and re-installed r, rstudio, and all packages.

Any ideas?

  • This is likely a problem in one of the dependencies. Can you load `httpuv`, `jsonlite`, `httr` and `devtools` and `openssl`? – Jeroen Ooms Mar 22 '16 at 13:51
  • The problem has resurfaced. I am using: opencpu 1.6.1 httpuv 1.3.3 jsonlite 1.2 httr 1.2.1 devtools 1.12.0 openssl 0.9.6 – MikeP Feb 07 '17 at 20:10
