Thank you for the detailed information. I will cover your questions one by one.
First, you said that the initial installation failed. In this case you should have been provided with the opportunity to submit the error to Telerik. I tried to find errors submitted from your user but I didn't find any. Submitting these error reports helps us to identify the reason for the problem that you encounter.
Second, we don't have unified uninstaller currently but we are working on a new utility that will provide such functionality. It will be available for all users shortly.
Next, the problem that you have encountered in Visual Studio 2010 is caused because the VS extensions that you have tried to use haven't installed properly. To resolve the issue I suggest you to reinstall just the VS extensions which is fast and easy. Here are the steps that you need:
- Start Visual Studio and launch the Extension Manager;
- Uninstall Telerik VS extensions and restart the IDE;
- Launch Extension Manager again and switch to the Online Gallery tab;
- Search for Telerik VSExtensions and install all that you need;
I hope this helps.
