Dynamics ax enterprise portal tools

After installing dynamics ax enterprise portal tools, open vs2008 and report an error saying that the add-in of dynamics ax enterprise portal experienced an unexpected error. Restart Vs and click OK, an error code 80070075 is reported for an invalid parameter. Ask if you want to remove add-in. After clicking "no", enter vs2008. use the tool-> external connection.ProgramManager. When the add-in function of dynamics ax enterprise portal tools is enabled, the preceding error is returned.
This add-in is a bridge between ax's Development Environment AOT and vs2008. If you do not enable this add-in, the contact between vs2008 and AOT will be less convenient, the Web usercontrol of ax cannot be directly imported to the corresponding node of AOT, or the user control in AOT cannot be directly imported to vs for modification.

Solution: Install SP1.

I don't know why this problem occurs if I don't install SP1. I only need to install vs2008 and I don't have to install vs2008 SP1. It seems that Microsoft can install patches well.
Since EP is web-based development, you must install the Web Developer component of vs2008.
