Frequent NSIS Error

[essemar]

This is similar to a previous post (http://forums.winamp.com/showthread....ght=nsis+error). I seem to be having the same sort of problem.

I keep getting the following error on many different files I've tried to install:

NSIS Error

The installer you are trying to use is corrupted or incomplete. Thes 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 /NCRC command line switch (NOT RECOMMENTED).

The first time it happened was trying to install the latest version of Azureus. I downloaded an older version, which installed fine, had it auto-update, and that worked.

The next was rarx. I can't remember how I got it to eventually install, but I did finally get it to work.

I've gotten this error trying to install new drivers for my Philips Shoqbox.

Most recently, and frustratingly, I get this error with DefilerPak and vlc. (I can listen to my .avi files, but I want to watch them too.)

Every file I download, I scan with Avast(hey, it's free) to make sure it's virus free, so it shouldn't be that. The first couple times this happened, I was willing to believer there was some sort of corruption somewhere, even when I tried downloading the file multiple times from multiple mirrors.

Now it's getting to the point where I think there must be something wrong with how my 'puter interacts with NSIS files. I ran a Kaspersky virus scan (from their website) in addition to my Avast. All clean. I ran Microsoft Antispyware and found nothing. Finally, I ran chkdsk. No problems there.

Could it be some sort of decompression issue? When I was trying to install Defiler and got the above error message with the self-executable, I tried downloading a .zip version of the installer. When I used the windows 'extract all' command on it, I got this error:

Once again, same problem from multiple downloads and multiple mirrors. Also, I just uncompressed a large batch of files I had archived with no troubles.

Sorry if this isn't the right place to post this problem, but I've tried a few other places, and no one seems to have any advice beyond what I've already tried.

Any of you have any ideas?

thanks,
