i solved it

first Perfectly uninstall the previous version of Atlas (06 Jan/06 March)

second Clean the registry (ex. use registry cleaning program)

finally Attempt to install again

Glad to hear it!

I've also heard from the team that clearing your browser cache first may also solve the problem so others having problems may want to give that a try.

Had the same problem here, over and over, no matter what/when I downloaded the AtlasSetup.msi file it was always corrupt.

I was able to get around by doing the following:

Instead of "saving" the download the my desktop and then running the .MSI file, I just "opened" the file using IE.  Not sure why it worked, but it worked!

I finally managed to download a good version a few days ago.

eyeborg: I think you may have just got lucky and it just happened to be when you'd given up saving the file first - when it was failing for me, attempting to run the install without saving it first caused it to come up with a security error (missing certificate I think from memory) - I think the person who mentioned earlier about "Unknown publisher" was onto something there: that's definitely one difference between the version that works and the one that doesn't.

I don't know if dud files were being cached on a proxy server somewhere or what, it was very strange.

But all's well that ends.

Hi all,

I cannot install Atlas either - I tried to download it several times from different locations, cleaned up IE cache but with no success. I've never faced with such problems before, probably Atlas team should re-release the package but with different name and location?

Thanks.
