"the error code 2869" while running installations in Vista
I have run into interesting problem in Windows Vista, while I was installing Web Service Software Factory and GAT I kept getting 2869 error code, followed by a few empty 'OK' prompts.
It looks like this error is due to the installation package requiring administrative rights. In my case installation package was denied contact with Visual Studio 2005.
There are several ways to fix this problem:
1. create a batch file containing msi package, and run it as Administrator
batch file will contain following line: msiexec /i {package.msi}
2. run msi from the with elevated privileges command prompt.
Find your "Command Prompt", typically located in: %SystemRoot%\system32\cmd.exe (or just search for Command Prompt); right click on it and select "Run as Administrator", and then navigate to your msi file
