I have a project, in VS 2005, which has a console application and a setup project associated to install the application. I also have an installer class in the console application that the setup project will use to do some validation before installation. Those tasks are checking the database connection string and checking some directory locations to make sure they exist prior to installation.
I am getting an error code of 2869 when I try to install the application. All the code is written in C#. I have googled for this error code on Windows XP, but only found articles that deal with Vista and Windows 7. Any ideas what might be happening? Is there a workaround?

The C:\Windows\Installer folder contains Windows installer cache, it's used to store important files for applications installed using the Windows Installer technology and should not be deleted. The installer cache is used to maintain (remove / update) the applications and patches installed on the computer.
After your computer applies a Windows patch, the patch file along with other files related to the installation are cached in the hidden system folder C:\Windows\Installer\$PatchCache$. The files in this cache are mainly used to roll the system back when a patch is uninstalled.
Step 2: Input the command “rmdir /s /q C:\Windows\Installer” in the prompted Command Prompt and hit Enter to execute it. Then the C:\Windows\Installer directory and folder will be deleted.
Deleting files from the WinSxS folder or deleting the entire WinSxS folder may severely damage your system so that your PC might not boot and make it impossible to update.
This won't help with fixing the installer code, but just in case this happens to anyone when doing in install on a Windows 2008 Server you probably need to run the installer from an elevated command prompt:
