I have a Windows XP Pro computer that suddenly cannot open any executable files like e-mail, internet, various programs on the computer. It comes up with the open with window asking what program is associated with the file. The only thing that has been done is I have been trying to resync a program on the computer with a database that resides on the file server. This apparently finished and was working then the next day this started. Any suggestions to fix this would be greatly appreciated.
