Today HTML help stopped working. The menu command "Help > Html help" usually brings up my default web browser (Opera 9.26), but now R gives the error Error: file association for 'doc\html\index.html' not available or invalid If I try the same menu command a second time, R crashes with the message The instruction at "0x7c9106c3" referenced memory at "0x7c9f4302". The memory could not be "written". The same problem occurs when calling help from the command line, e.g. with ?license I'm running R 2.6.2 on Windows XP SP2. Googling for the error turns up nothing, and I have no idea where to look for further diagnosis. I have uninstalled, deleted the R package directories, and checked the registry for metions of "\R\", but the problem remains. I can't think of any unusual changes I made before this problem arose.
Try re-setting the file association for .html files -- it looks as if it has been corrupted (not by R).
