Installer integrity check has failed error

Asked By JamesMurphy 0 points N/A Posted on - 08/08/2011

I recently downloaded NSIS on my Windows Vista machine.  After this install I rebooted my machine and after a reboot I tried to install software application, and it throws up an error message.

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: http://nsis.sf.net/NSIS_Error

The NSIS error keeps coming up anytime I try to install any software. Does this mean that I have a virus on my machine after I installed the software? Or does it mean that my installer is corrupt?

Use chkdsk to scan your hard drive.

Try to update your antivirus and then run a full scan on your computer. Virus behaviors appear in many forms and usually display different forms and sets of misleading information and messages.The error you receive might be the cause of an incomplete download. Be sure to download the file or the installer completely. Or download NSIS from this website:

http://nsis.sourceforge.net/Download

Download only from trusted website. We, in techyv do not recommend using any illegal tools for downloading softwares.
