nsis error
 

I have downloaded 4.6 basic for windows xp and saved the exe file to my desktop. When I double click on the icon it gives me the following error:
NSIS Error:
The isntaler you are trying to use is corrupted or incomplete. This could be the result of a damaged disk, a failed download or a virus. You may want to contact the author of this installer to obtain a new copy. It may be possible to skip this check using the /NRCR command line switch (not recommended).

I re-downloaded the file 4 times and still get this message.

1. 1st install up to date Java!: Java 1.5 (take the JRE)

2. There is an alternative installer. You just unzip it & use it. See Here about other version.

The link you submitted to download a zip file does not go anywhere. Do you have another location for this zip?

Sorry about that, try again.
