Keep in mind that the version Fernando uploaded here is just for VS2008, we will release a DeKlarit 4.5 for VS2005 with the same functionality the one for 2008 has in a few days. DeKlarit 4.5 will probably be the last version for VS2005 we will ship, we'll keep updating the VS2008 version so start planning your migration.
If you have DeKlarit 4.3 or prior on your machine you can install 4.5 for VS2008 without the need to uninstall 4.3. The whole idea is to have your VS2005 with DK 4.3 now (4.5 for VS2005 in a few days) and DK 4.5 for VS2008 in the same box.
To migrate to VS2008 just install DeKlarit 4.5 for VS2008, create a new DeKlarit project and import your components from your model. The import and export process are the same to previous versions so you can export from VS2005 and import in VS2008 and vice versa with no problems.
