Installation is quite straight forward.
For the installer version just run the setup.exe from the installer. That is all you need to do.
You can now start visual studio or your IDE and add your already checked out CVS project to source control.
Alternative Zip version
For the zip version: Unzip the igloo.zip package.
If you have the zip version then you need to run the install.bat script which will register the igloo.dll as the SCC source control provider
Once the registry entries have been set then you can start visual studio or your IDE and add your already checked out CVS project to source control.
Note: If you have Source Safe installed and you want to switch back to it run the switchToSourceSafe.vbs script. This is only available in the zip version
