Hello,

We had a problem with our Windows 7 installer, first reported on 16th July 
(i.e. Tuesday) displaying an error dialog when run, stating:

  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

This error occurred each time it was downloaded and run, on multiple 
different machines (including ones with only the built in Windows anti-virus 
software, so I don't think any third party anti-virus software is to blame).

We didn't have this issue with our Windows 10 installer (although the error 
will be displayed on Windows 10, if you mistakenly use the Windows 7 
installer on it).


I found some emails from 23rd October 2017 saying this had happened in the 
past which suggested a corrupt version may have been downloaded.

In our case, I went to the CAT page for the installer and edited the profile, 
made no changes but then saved it.  After doing this, the downloads all 
succeed, on the same machines, with an installer that is 10kB larger (same as 
the previous report).  My suspicion is that a corrupt installer was created 
and cached and editing the profile forced a rebuild - I don't think the 
client machine was to blame as all the affected machines are now working.

I have a copy of the installer before and after it being fixed, if they're of 
interest - the last broken one downloaded at 14:51 BST (GMT+01) today (19th 
July - Friday) and the fixed one at 14:52.  Are they of interest to 
investigate this or is it just a spurious problem?

  - Bob
