It says
Unable to load development environment dll.

Actions done to remove problem

1. Removed entire visual studio 6 and reinstalled it.
2. Problem is same.

3. Dir Printout in which MS Visual InterDev is installed is given below.
4. Double clicking MSE.EXE starts it but I am not able to start it with double
clicking DEVENV.EXE
5. I am not able to make projects from Templates, as menu items are disabled.
