RStudio just started reporting the error below:
The ordinal 4430 could not be located in the dynamic link library: ssleay32.dll
This doesn't strike me as an error related to R or RStudio. Googling a bit suggest it has to do with windows libraries.
Here's a discussion related to ssleay32.dll:
In particular, RStudio itself does not bundle this library; rather, it statically links to it so I suspect whatever is attempting to load this library is something separate from RStudio.
