The real reason why QQ2009 can't be used under Windows 7

I used to have a habit of installing QQ on other disks, because I kept all the chat record expressions, so after reinstalling the system, I can cover it and install it. . But after installing Windows7, I installed QQ2009 and found that it can't be used. No matter how I get it, there are problems. Later, the last move is to install according to the default installation path of QQ. It can be used! And QQ2009 has the advantage that you can set the storage path of chat records separately, so it is still very good!
So if everyone's QQ2009 can not be used, it is installed to the default path, you can definitely use!
