I purchased a copy of Engineer's Toolset v10 a couple years ago and installed it on a Win2003 server. I recently reinstalled/ migrated the application to a new Win2012 R2 server but the application is extremely slow (it takes 1-2 minutes to open anything). Does anyone know if Version 10 does not support Win2012? Unfortunately, I no longer have maintenance so I can not upgrade to version 11.
