handling a 32 bit app in 2008 R2 over RDS

Hello,

At my company we have a rather strict 2008 R2 64-bit environment, and are planning to move off of Citrix in favor of RDS. We have a 32-bit financial application called Epicor that makes 32bit calls from its DLLs, which don't get translated well in a 64 bit environment at all. Data gets corrupted and of course that's not workable.

We really need some ideas on how to handle this - our current thoughts do we keep them on 32 bit 2003 servers as they are currently and have a desktop TS client in RDS. OR install it locally in XP mode. But those ideas are clunky for different reasons. Has anyone had any success wrapping unusual 32 bit apps in a 64 bit environment otherwise?

Thanks much for your thoughts!

Unfortunately when I've come across this recently, the most seamless option has been to publish the application (RemoteApp) from a 2008 RTM (i.e. non-SP2) server into the SP2 farm.

Still a tad clunky, but better than trying to keep 2003 alongside, generally.

Application Virtualization should address this issue

Yes - if you have the licenses, then App-V is definately useful providing the application doesn't install device drivers of any kind.

There are other limitations, so worth testing first in any case.

Microsoft now includes App-V for RDS with the RDS CALs for free. If App-V is the solution, you already have free access to it.

Thanks for the thoughts - for what I am seeing, App-V would work well. If we make an environment ready for one app (for now), that wouldn't present a problem publishing that over RDS, right?
