Internet Explorer - Unity Player Launch error

Hello,
I am experiencing a problem with Unity Web Player launching in IE 7.

On Windows XP (latest updates) and IE 7 (7.0.5730.11), I get the following error:

“Error launching Unity Player” with a link to “Error Details”:

“Failed to decompress web stream because of insufficient memory.”

The PC which I am using to test this has 2 GB of RAM; the error message pops up pretty quickly on beginning the download…it appears *.unity3d file continues to download, but is not accessible after the error message shows up.

To further complicate this, a co-worker with a Macbook Pro using XP in Boot Camp can access the same file without issue, but encounters the same error message on her desktop PC.

Any suggestions?

Thank you in advance.

try other webplayers because it could just be that one webplayer file.
