I just uninstalled R 2.7.2 on Windows XP after having installed R 2.8.0 The uninstaller removed the String values HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\Current Version HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath despite the fact that they pointed to R 2.8.0 The uninstaller did not remove the key HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 (and all the values in that key)
I think the uninstaller should only remove the Current Version entry if it points to its own version. In a second attempt, the 2.7.2 uninstaller removed the key HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 (which is what it should do) but it still removed the HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\Current Version HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\InstallPath values. It should not have removed these keys. Sometimes this does not happen, and I have not found a consistent explanation when it happens and when not. Sometimes also running RSetReg.exe creates a second entry like HKEY_LOCAL_MACHINE\SOFTWARE\R-core\R\2.7.2 which has identical content with the first one. The registry really looks like having 2 identical entries. Is this something which I should file as a bug? -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at http://sunsite.univie.ac.at Phone: +43-1-4277-39464 Fax: +43-1-4277-39459 ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
