This error may also happen in the middle of a session.In some cases where we have tracked this down, it was due to bugs in the video driver on the system in question: it makes changes to the floating point control word which are incompatible with R.Running R does need access to a writable temporary directory and to a home directory, and in the last resort these are taken to be the current directory.

Unfortunately, because DLLs may themselves load other DLLs it is not possible for R to track which DLL caused the problem.

which indicates that R has taken action to correct the action of some (non-R) DLL which has just been loaded and has changed the floating point control word (in its initialization code) to a setting incompatible with that needed for R.

This is not good practice on the part of the DLL, and often indicates that it needs to be updated.

After installation you should choose a working directory for R.

You will have a shortcut to on your desktop and/or somewhere on the Start menu file tree, and perhaps also in the Quick Launch part of the taskbar (Vista and earlier). and change the ‘Start in’ field to your working directory.

Uninstalling R only removes files from the initial installation, not (for example) packages you have installed or updated.

If all else fails, you can just delete the whole directory in which R was installed. For most people the best thing to do is to uninstall R (see the previous Q), install the new version, copy any installed packages to the library folder in the new installation, run in the new R and then delete anything left of the old installation.

Just double-click on the shortcut you prepared at installation.

If you want to set up another project, make a new shortcut or use the existing one and change the ‘Start in’ field of the Properties.

Current binary versions of R are known to run on Windows 7 or later, including on 64-bit versions: See Can I use R on 64-bit Windows? The last version known to run on Windows 2000 was 2.12.2. We only test on versions of Windows currently supported by Microsoft, mainly 64-bit Windows 7, Windows Server 2008 and Windows 10.
