"Can't find init.tcl" on Windows

[MikeInnes]

When I run using Tk I get the error

ERROR: TclError(
"error initializing Tcl: Can't find a usable init.tcl in the following directories: 
    {C:\\Ruby200-x64\\share\\tcl} C:/Ruby200-x64/share/tcl8.5 C:/Ruby200-x64/lib/tcl8.5 C:/Users/Mike/Desktop/julia-05c6461b55/lib/tcl8.5 C:/Users/Mike/Desktop/lib/tcl8.5 C:/Users/Mike/Desktop/julia-05c6461b55/library C:/Users/Mike/Desktop/library C:/Users/Mike/Desktop/tcl8.5.12/library C:/Users/Mike/tcl8.5.12/library

    This probably means that Tcl wasn't installed properly.

Installing ActiveTCL didn't help, and copying its init.tcl file to one of these locations caused using Tk to hang until I reinstalled Julia. For what it's worth, git gui (using Tk) runs fine on my system.

I encounter the same problem on latest Julia release (0.3.2) Win7 x64 :

After deleting .julia totally, problem solved! @one-more-minute have you tried that?

There still seems to be some weird stuff happening with Pkg, @StefanKarpinski

[cmey]

@one-more-minute, Otherwise, my Julia seems to be looking into my Anaconda install path, maybe try to install Anaconda?

[MikeInnes]

Oh, I gave up on both Windows and Tcl a long time ago, but glad you got yours working.

[joa-quim]

I'm still getting this error even after starting with a new .julia/v0.4 (didn't want to try the same with v0.3).
I also noticed one thing. I copied one init.tcl that I found in WinRPM into julia-0.3.4\lib\tcl8.5 and now it also complains that
version conflict for package \"Tcl\": have 8.5.2, need exactly 8.5.15\nversion conflict for package \"Tcl\": have 8.5.2, need exactly 8.5.15\
So the init.tcl in C:\j\.julia\v0.3\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\share\tcl8.5 does not go along with the dll in C:\j\.julia\v0.3\WinRPM\deps\usr\x86_64-w64-mingw32\sys-root\mingw\bin\tcl85.dll which claims to be version 8.5.2.15

[dchansen]

The issues seems to be that Julia finds a Tcl installation from another programming language (Python or Ruby for instance), which does not match the version needed for Tk.jl.
