PrimalScript 2011 and Windows 2003 Server (64 bit)

PrimalScript and PrimalForms 2011 make heavy use of the “sysnative” virtual folder to access 64 bit operating system tools and files.

Under the 64 bit versions of Windows 2003 Server and Windows XP that virtual folder is not available by default. In order to ensure proper installation and operation we recommend that you install the following Microsoft hotfix prior to installing PrimalScript 2011 or PrimalForms 2011.
