The reason this happens is because Internet Explorer makes a determination that VIP files are Zip files. More details on how IE does this are here.
The quick fix:
- Goto your Internet Explorer>Internet Options>Security Tab
- Make sure the Internet zone is highlighted
- Under: Security level for this zone, change the slider bar from Medium-High to -> Medium
- Click OK
This problem only happens in IE. We understand that It might not be possible to switch the security level because of your IT dept. restrictions, but if you can, then this is the way to go.
If you are a webmaster:
The solution is a server side change that you, as a webmaster, need to make to your web server configuration. The easiest way to do this is with an .htaccess file (on an Apache web server). Here is a link to some instructions on how to do this:
Adding Mime Types (external link)
Based on those instructions, simply add the following line to your .htaccess file:
AddType application/octet-stream .vip .ogp
If you don't have access to your web server files to make this change, simply ask your web hosting company or whoever manages your web server to make this change for you. It should be a simple task and most administrators know how to do this.
