Marcelo, If you have installed ActiveTcl with administrator priveliges, it should create an entry in the Windows Registry, and then limmaGUI should find it and automatically add the Tcl Path so that limmaGUI can find Tktable and BWidget in C:\Tcl\lib\ or wherever. But maybe it's getting confused between registry entries for "all users" and registry entries for "just you". You could try the following from the R prompt before you run limmaGUI. If they work, you could even add them into your .Rprofile so they run every time you start R. Sys.putenv("TCL_LIBRARY"="C:/Tcl/lib") Sys.putenv("MY_TCLTK"="Yes") addTclPath("C:/Tcl/lib") require(tcltk) If you still get the warning about ActiveTcl, you may be able to ignore and just start limmaGUI() Let me know if this works. If it doesn't work, please tell me what happens when you type: require(tcltk) tclvalue("auto_path") Regards, James

James, I install the ActiveTcl not with administrator account, but with my account. However, I have administratives privilegies! I have full control and I am the administrator of my computer. When I type: Sys.putenv("TCL_LIBRARY"="C:/Tcl/lib") Sys.putenv("MY_TCLTK"="Yes") addTclPath("C:/Tcl/lib") require(tcltk) in the R prompt, I still the warning message, but the limmaGUI start very good. yeeeahhh! I exit from R and restart it. When I type require(tcltk), it is the result: > require(tcltk) Loading required package: tcltk [1] TRUE When I type tclvalue("auto_path"), it is the result: > tclvalue("auto_path") [1] "{C:\\PROGRA~1\\R\\rw1071/Tcl/lib/tcl8.4} C:/PROGRA~1/R/rw1071/Tcl/lib ./lib C:/PROGRA~1/R/rw1071/Tcl/lib/tk8.4 C:/PROGRA~1/R/rw1071/library/tcltk/exec" Does the second result seem to indicate that the path for the dir of the ActivTcl is wrong in the registry or in R. Correct? Do you know which is the key in the registry for the ActivTcl? I can alter it with safety. Thanks very good!
