Notes to Inno Setup 3.x Users

At the time I wrote this document, Inno Setup 3.0.3-beta has been released. If you are using it, or a any Inno Setup 3.x versions, then you will need to make a little change to your R.iss under R-1.6.0/src/gnuwin32/installer. Line 12 (your R.iss may be different) says:

AlwaysCreateUninstallIcon = YES

you need to remove this line. AlwaysCreateUninstallIcon option is no longer supported in Inno Setup 3.x or later. If you want this option, you can put something like:

Name: "{group}\R 1.6.0"; Filename: "{uninstallexe}"

into the [Icons] block.
