Windows build fail to find exe file that was just installed

I am having trouble to run my CI tests on Windows using travis. One of the failed builds can be found here

the log shows that octave.portable was successfully installed at C:\ProgramData\chocolatey\lib\octave.portable\tools and a shim was also created:

“Added C:\ProgramData\chocolatey\bin\octave.exe shim pointed to ‘…\lib\octave.portable\tools\octave\bin\octave-cli.exe’.”

however, when I call either octave-cli.exe or octave.exe, it complains that “C:\ProgramData\chocolatey\lib\octave.portable\tools\octave\bin\octave-cli.exe” can not be found.

is this a known issue?
