The following is a detailed explanation:
Recently, QQ was installed after reinstalling xp on the computer, prompting that "the installation package was illegally changed, resulting in the installation failure. Please download the latest installation package from official website and reinstall it. " However, this computer was first prompted by QQ to be illegal, but it can be reinstalled after installing the driver with the driver. Later, it was illegal to install it on other computers with different configurations (both the virtual machine and my computer have tried it). However, the company's previous computers can use QQ.
Test start:
1. Install the latest version of QQ of xp (original version) in the virtual machine, and the md5 check has not changed. Download from multiple channels, download from multiple tools, md5 is the same. It is still illegal to install on xp system. Initially, QQ does not support xp.
2. Found a problem with the newly installed xp certificate. All https websites prompt that the certificate is invalid. "windows does not have enough information to verify the certificate."
Look at xp and you can install QQ's computer certificate. Everything is normal. So the new xp starts with the certificate, and all kinds of tests can't be solved.
3. Download and install KB931125-rootsupd until Baidu search has an answer in it Sky. Open the download point, there is no response. After restarting xp, the certificate is normal. Click QQ again and it will be installed normally. The driver's life driver probably installed this patch automatically and can use QQ.
4. Test this update package again. I used three versions of xp, the original xp, the ghost version and the ylmf installation version, all of which were fine. It is illegal to install QQ directly after installing the system. Open kb931125-rootsupd, just flash in the task manager without any interface and prompts, and then QQ installation will be normal.
