A new article on HorizonFlux should get everyones attention who’s involved in Windows Migration projects. Tim Arenz again has published a great read on VMware ThinApp. Here’s a quick quote of his article but please visit his blog an learn how ThinApp can help you within a Windows 7 migration.
However other issues aren’t fixable at all. If an application relies on 16-bit components or is a 16-bit application itself and you want to migrate to a 64-bit version of Windows you are out of luck. The application simply will not work. You could however use VMware Workstation orView to deploy 32-bit virtual Windows machines for your legacy 16-bit applications. Another example for an application which will probably not work if it depends on APIs which are deprecated or undocumented and therefore not available or working different in Windows 7.
Other reasons why an application might fail to work on Windows 7 like deprecated .dll files, hard-coded locations and dependencies to specific versions of Internet Explorer are a perfect fit for ThinApp!
