Win7 system open QQ prompt configuration is incorrect reason and solution

  

One of the reasons: your computer's Windows Installer service is not turned on.

Solution:

Open the Control Panel → Manage & Rarr; Service, open the Windows Installer service, and set it to automatic, then restart the computer.

Cause two: The Visual Studio runtime is not installed on your computer.

The application was developed in Visual Studio 2005 and above and relies on the appropriate runtime library that is not installed on your computer. (For VC6 or VS2003 developed applications, if the library file is missing, it will prompt the lack of "**.dll", but VS2005 or VS2008 only prompts "due to the application configuration is incorrect ……". )

Solution:

1. Instead of reinstalling the application, it is not to reinstall the system, but to install the corresponding runtime (Microsoft Visual C++ 20** Redistributable Package, ie vcredist_x86. Exe.

2. It is a bit difficult to distinguish which version of VS you are developing. Even some software is developed in multiple versions, so many vcredist_x86.exe are installed, they are compatible with each other. It will solve the same kind of problems with most of the software on your computer.

The following is “20**” on behalf of “2005” or “2008” or “2009” or “2010”.

Required installation package

Only one file ——vcredist_x86.exe downloaded from Microsoft official website download center

1. Open the control panel → management tool → Service if Windows If the Installer service is not enabled, set it to automatic and restart the computer. If it does not solve the problem, continue.

2, you can initially determine which version of VS your program is developed.

(Open the directory where the application is located, search for the file with mfc or msvc at the beginning, if any, please check the version of the file to know the version of VC. Please see the figure below, 8 indicates VC8.0 development, and 9 indicates VC9.0 development. )

The VC version of VS2003 is VC.1,

The VC version of VS2005 is vc8.0,

The VC version of VS2008 is vC9.0.

3, control panel "Add /Remove Programs" check whether the machine is installed Microsoft Visual C++ 20** Redistributable Package.
