Hi folks! Today being the official launch party for Windows 7, I thought it would be a good time to give everyone an update on where we stand with client OS support for Access Gateway (AG).
Let me start off by saying that we were hoping to support 64-bit operating systems much sooner, but we had some unanticipated challenges that expanded the scope of effort required. Getting all of our Access Gateway plug-ins to support 64-bit Vista, as well as Windows 7 and MacOS, has been and continues to be a top priority for us this year. It’s also critically important that we fit into the Citrix Receiver framework for delivering all the various Citrix plug-ins to the end user. We’re nearly there.
I’m pleased to announce that we are releasing today version 4.6.1 of Access Gateway, Standard Edition which offers full support for 64-bit Windows Vista, Windows 7 32-bit and 64-bit, and MacOS. You can get the clients and appliance firmware now from the Citrix.com downloads area: http://www.citrix.com/download/
As you know, we have three distinct variants of Access Gateway: Standard, Advanced and Enterprise, each of which has a separate lineage and uses different client protocols & endpoint analysis features. We are planning to deliver Win7, 64-bit and MacOS support for all three editions.
Vista 64-bit, Windows 7 & IE8
- AG Standard supports 64-bit Vista and Windows 7 today, using version 4.6.1.
- AG Advanced Edition users can log on from 64-bit machines if the appliance is upgraded to 4.6.1, but full support for endpoint analysis and IE8 is not available until AAC Hotfix 5, due out in early January.
- AG Enterprise Edition is expected to include a new 64-bit capable client in version 9.1.100, ETA is December.
Last month, we announced the availability of our first Access Gateway Plug-in for MacOS, which now connects to AG Standard Edition (4.6 or later) and Enterprise Edition (9.1.98 or later). Support for Advanced Edition is expected by January with AAC Hotfix 5. As we were closing down the release, Apple released their “Snow Leopard” (10.6) version ahead of schedule. We were planning not to offer 10.6 support until a few months later, because we were expecting this to be another large effort pertaining to 64-bit support. However, Apple did not enable 64-bit kernel mode by default in client machines, only on their XServe platform. This is good news for us, because the MacOS client seems to be working fine on 10.6 with the default 32-bit kernel mode.
One thing that makes 64-bit support on MacOS different from 64-bit Windows: with MacOS users can run 64-bit applications even if the kernel is running in 32-bit mode. Nevertheless, we do plan on supporting 64-bit kernel mode on the Mac with our next release of the Mac plug-in in Q1 of next year.
To avoid prolonging our release schedules any longer, we made a couple of tough trade-offs regarding older operating systems. We decided that we will not be able to provide official support for:
- Windows XP 64-bit
- MacOS 10.4 (“Tiger”)
(I’ve heard anecdotally that the 64-bit Vista client actually does work on XP 64-bit, but we have not fully tested it and we are not officially supporting it.)
