For information on future support products and dates, please work with your SE; unfortunately, anything else is guessing. Unofficially it should be available by the end of April 2012; however, that can change.
I found the fix for this on accident actually...With Windows 7 32-bit or 64-bit there has to be a registry entry added. The path to the registry key is HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\WinLogon\DefaultDomainName. By default the Default Domain Name entry is missing from Win7. Add a new string value and type in DefaultDomainName. In the value data enter your Domain (ours is called Complink for instance) and save the the new string value. Install host checker and use the 32-bit version of IE to sign into your SVW. We are currently using this with no issues.
Thank you for that nifty option to waiting for this to be available and supported. Please remember that it is not officially supported as a platform at this time; but glad to hear it is working for you in the interim.
Please do not download the IVE OS version 7.2R1 which is on the portal as of today as we have found some issues and we are coming out with a fix in next few days and the release version will be - 7.2R1.1.
Please wait for this 7.1 R1.1 to be posted. The tentative time for this release is in next 24 - 48 hours.
