On some products (e.g. multi-attribute), the downloaded .exe files are being corrupted with additional html content being added. Other .exe downloads are fine. This WAS working, but was being administered by a contractor and his gurus who have now deserted the scene. So now we are picking up the pieces.
Downloading the file via ftp works fine. Have reproduced with single attribute product. Not afraid to get into the databases to provide diagnostics.

Using ZC 1.3.6 with "Download by Redirect" off, as otherwise, top and bottom of file have extra html.

All help appreciated.
