Migrating from WinDev 7 and up

 

WinDev 2024 migrates automatically from older versions.

Easycom has a unique DLL for each WinDev version (eac750as.dll, eac800as.dll, … eac2800as.dll, eac2900as.dll).
So, different versions can be installed on the same system.

 

Easycom server must be updated to be compliant with latest WinDev versions.

Newest Easycom server versions are compatible with ancient WinDev versions.
