Error Installing standalone application in Windows 7: Aborting installation: could not spawn unzip process

Recently when I tried to install a stand-alone application complied by MATLAB Component Runtime, it gave me the following error message:

aborting installation: could not spawn unzip process.

The application is successfully installed Windows XP. The error happened when installing in Windows 7, does anybody have any idea how to solve it?

A couple of ideas come to mind:

1. How was the unzipping happening? Was it looking for a particular program? Is it trying to write into a folder where it doesn't have permissions to write?
2. Have you tried running the installation with elevated permissions? Windows 7 has a different security setup than Windows XP. A quick way to try this out is to launch a command window with adminstrator privileges (hover over cmd, right click, "Run as Adminstrator", then launch the program in that prompt) and see if the error persists.
3. A variation of the above is to start the install with elevated permissions. Select the installer program, right click it and say "run as Administrator".

Tip number 2 of Jason Ross' answer above helped me.

I found that I needed to re-run the MCR installer using the cmd prompt under administrator mode (even though my user has admin rights), and ALSO run the application via admin cmd prompt as well.

The cmd

pushd

helped speed up navigation to relevant folders

Thanks!

Was the application compiled for Windows 32, and are you trying to install it on Windows 64 ?

I do not know which unzip program is used by MCR, but see this previous discussion: http://www.mathworks.com/matlabcentral/answers/27979-pkunzip-for-x64-matlab
