When opening any file of office2007 to prompt for installation, VisProWW.msi can't be found during installation, which is invalid after reinstallation, and it is not good to choose to install all of them. The solution is as follows:

1, open 360 Security Guard, and click Function Book.

2. In the system tool, click on the registry to slim down.

3. Click Scan Now.

4. After scanning, click Clear Now. After cleaning, Office2007 can be installed normally. It is best to restart after cleaning.
