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
(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?
