I cannot install Mosek.jl on a Windows 7 64 bit under Julia v0.5.2. I have downloaded and installed Mosek 8.0, mosek.exe is on the PATH and ENV contains the following keys:

"MOSEK_8_0_BINDIR"        => "C:\\Program Files\\Mosek\\8\\tools\\platform\\win64x86\\bin"
"MOSEK_8_0_EXE"           => "C:\\Program Files\\Mosek\\8\\tools\\platform\\win64x86\\bin\\mosek.exe"
"MOSEK_8_0_INSTALLDIR"    => "C:\\Program Files\\Mosek\\8"

Pkg.build instead attemps to download and install Mosek 8.1.0 and fails:

julia> Pkg.build("Mosek")

The installation is flawless on 0.6 and uses the system-wide version of Mosek.

It looks like this is probably a bug with the way installation is handled in older versions of Mosek.jl. Unfortunately, it looks like they stopped supporting Julia 0.5 as of about a week ago. I think your best bet is filing an issue there; maybe they would backport the build fix to a 0.5-compatible tag.

If you are okay upgrading to 0.6, now is a good time, but I understand there are reasons why that might not be possible in your case.
