When installing MOSS 2007 Beta2 on an SPS2003 environment during an upgrade attempt, I received the following error:
Microsoft Office Sharepoint Server 2007 (Beta)Setup ErrorsSetup is unable to proceed due to the following error(s):This product requires Windows Workflow Foundation Beta 2 (Build 3.0.3807.7 or later).Please refer to this readme file for instructions to obtain these pre-requisites. Correct the issue(s) listed above and re-run setup.
My action steps were as follows:
1. Remove .NET 3.0 framework using the Pre-released Microsoft .NET Framework 3.0 Uninstall Tool
2. Install Windows Workflow Foundation Runtime Components Beta 2_2(EN) for x86.exe
After I completed these steps I was able to install MOSS 2007 Beta 2.
