x64 apps are not showing on the streaming portal on a x64 machine

Products

• Workspace Streaming (formerly AppStream)

Issue/Introduction

When opening the streaming portal on an x64 machine in IE11 you can see only x86 applications in the portal

Cause

The streaming portal expect to see WOW64 in the User Agent String from the browser. If there is not WOW64 in the sting then the streaming portal thinks the system you are coming from is an x86 system.

To view your current browsers User Agent string you can view it through the developer tools and run a network trace from IE to see what the agent string is being sent, or you can also go to http://www.useragentstring.com/ 

A sample of a User Agent string below:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0

Resolution

The wow64 token is missing from the User Agent String. You can force that by adding the WOW64 string key to HKCU\Software\Microsoft\Windows\CurrentVersion\InternetSettings\5.0\User Agent\Post Platform  or [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent]




To add the String value to the following:

1. Open registry editor (regedit.exe)
2. browse to [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent]
3. highligh the Post Platform key
4. in the right pane right click and add string value
5. type WOW64 in the name and leave the data blank
6. close registry editor
7. close all browser sessions
8. browse to the streaming portal and you should see x64 apps now.
