Prerequisite Kits HomeInstallation of an OSIsoft product on Windows relies on the presence of Microsoft operating system components such as the Microsoft .NET Framework and Microsoft run time libraries.
OSIsoft Prerequisite Kits are available in three packages that verify and install the needed operating system prerequisites:
All three Prerequisite Kits contain both 32-bit and 64-bit installation redistributables.
- Online (Recommended): For installation on a computer connected to the internet. This kit connects to Microsoft sites in order to download .NET Framework 3.5 for the operating system on which it is run. This is a bootstrapper kit that is much smaller than the Standalone kit.
- Standalone (Recommended): For installation on a computer that cannot connect to Microsoft sites, or for installations where such connection is not desirable. This is a full redistributable kit that is much larger than the Online kit.
- Legacy: This kit should only be used for installation on older operating systems where the OSIsoft products do not require .NET Framework 3.5.
See "Which Prerequisite Kit do I need?" for more detailed information on how to pick the kit that is right for you.
