I am not sure what you are trying. If you don't want to use RTC SCM in Visual Studio, you don't have to install the RTC VS client into Visual Studio. You could use the Eclipse client to version files - but probably not for Visual Studio projects, because the VS client knows about VS projects and handles all that.

Another option would be to work with the web client, downloading and uploading a file and change into SCM using the web client.
If you look at https://jazz.net/blog/index.php/2012/02/06/introducing-the-rational-team-concert-shell-integration-for-windows-explorer/ you can see that, for Windows Clients a shell integration is planned that might be another option, depending on what you try to achieve.

Hi,

using RTC to source control MS Visual Studio projects is done best with the RTC client installed in MS Visual Studio. This setup offers a lot of advantages and ease of use compared to any other approach.
That said, you have the following options:
- you can use SCM command line for versioning
- you can use RTC Eclipse Pending Changes View
- you can upgrade to RTC 4.0 (due out mid June) and use the Windows Shell Explorer.
Using the Web Browser you can version control and handle single documents and source code files, but it is not feasible for large solutions or source code projects.

All in all it is probably WAY easier to find out what exactly keeps you from wanting the RTC client in your MS Visual Studio and fixing that.
