Installation Problem of Ipopt

General Usage
1

If I use Julia installer 32 Bit I can install Ipopt by using command at Julia command prompt - Pkg.add(“Ipopt”) and it passes through Pkg.test(“Ipopt”). If I use Julia 64 bit I can’t install. Pkg.test(“Ipopt”) failed and gives ReadOnly Memory Problem. I am using Windows 10 64 bit. Both Julia 32 and 64 bit is working on it except Ipopt. There is no installation problem with Clp,Cbc,GLPK,NLopt. Why Ipopt?

If you give the full error message it would be much easier to help you.

You can find issues about this here and here. This comment from tkelman contains the code fragment that fixed it for me:

using WinRPM
pkgs = String[]
for pkg in eachline(WinRPM.installedlist)
    name = match(Regex("$(WinRPM.OS_ARCH)-(.*)"), last(split(pkg)))
    if name !== nothing && !isempty(WinRPM.lookup(name[1]))
        push!(pkgs, name[1])
    end
end
WinRPM.install(pkgs)

Its giving LoadError: ReadOnlyMemory Problem.
