Installing haskell ghc fails

1

I am trying to install Haskell-2012.4.0.0.exe on my computer running windows 7.

When I run the installer I get the following message and the installation fails,

Installer integrity check has failed. Common causes include
incomplete download and damaged media. Contact the
installer's author to obtain a new copy.

More information at:

How do I fix this issue and get it to install?

The error message suggests what is wrong - incomplete download and damaged media; Get a new copy! For what ever reason, it may appear that your download was not successful (maybe your internet connection dropped during download). So, re-download the installer and then try to install again.

I used the same installer to install it on another machine running windows 7 and it worked without any issues. – Ishan – 2013-04-18T06:27:51.537

Well, if you've tried again to install it and it still fails then consider your firewall or AV or any other similar programs (or even permissions) – Dave – 2013-04-18T08:09:20.640

I have been able to install haskell successfully. I found that changing the usb I used to copy the haskell setup installer from my computer to my usb to install on another computer fixed the issue. It seems that when I am copying the file to the usb, that it is not completely getting copying. – Ishan – 2013-04-20T04:44:38.133

You didn't mention this in your original post :-) – Dave – 2013-04-20T05:33:37.653
