Info

We added a Registry Entry to detect if eSO is already installed with the Browser (IE). The Standard and the Addon Setup have a unique value, which contain the Versionnumber, which can be helpful in case it´s also important to know which version the user has (force Update).

Technical

We are set the Following 2 Registry Entrys to support all the IE Versions (tested with IE6,8,9).

HKCU

"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\User Agent\\Post Platform"

"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\5.0\\User Agent\\Post Platform"

And, on X64 OS, additionally

"SOFTWARE\\WOW6432Node\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\5.0\\User Agent\\Post Platform"

Details Information can be found under:

The Values can be readed inside the UserAgent:

javascript:alert(navigator.userAgent)

Note

 The IE8 is supporting both Registry Entrys, which means the values are twice in the UserAgent
