Pick 1 or 2 of those programs in the list, and run it on them. Pick something of less importance, like driver detective. Run the program, and verify that it's removing the install files.
Thanks for your prompt reply. I just try and delete as mentioned, it did not solve the problem. I wonder what the windows installer is pointing to what, it did not have any error report but the syntax only. Well any further help from you all will be much appreciate.
