fragstats installation problem

when fragstats was installed, it cutomatically finished without imge attached,thanks, why  

Hi zhouxj,

It is difficult to say why you experienced that problem from just one picture of one installation dialog.
I don't know the Operating system or the build you are trying to install. Is the behavior consistent or it happened just once? Have you managed to get it to install after all? Did you get any warnings from Windows? Did you look into the system Event Log for messages related to this installer?
The executable is not signed (yet) so depending on your security settings Windows may refuse installation, although a courtesy message should have been displayed to tell you why. Usually, you should be given the opportunity to accept the risk and continue.
And finally, from reading the installation path it appears that you are trying to install the legacy 32-bit version on a 64-bit machine, or you've modified the path of the 64-bit version to go into the 32-bit Program Files (x86) folder.
If you're trying the 32-bit version I would suggest upgrading to the 64-bit one since it is more appropriate for your computer.

Cheers,
Eduard
