Each time you open the Excel2007 prompt to send a command to the program, there is a problem, to open two times to open, the following describes the solution to the problem.
The first scenario: the solution that masks DDE, which is what most people are in this situation, the solution:
Excel Options-Advanced-the bottom-most general-removes the "Ignore other applications using Dynamic Data Exchange (DDE)" Tick before it can be resolved.
The second case is because the VS2008 2010 is installed, so this situation is not solved with the scheme of blocking DDE.
Workaround for the second scenario: Excel Options-Add-ins-Select the-com add-in from the bottom "manage"-click to go-in the pop-up window you only need to select two items: Chinese translation Addin and office special Symbol Input add-in can be resolved by selecting OK. (Remove all COM add-ins related to VS)
