Install Microsoft. NETFramework3.5ServicePack1 and Return Error 1603.

After the server is upgraded to the system patch (360 installed), all. net websites cannot be opened and the system prompts"

Failed to execute the request because the application domain cannot be created. Error: 0x80070002 the system cannot find the specified file .", However, php and asp are normal, so it is determined that the. net framework is broken.

Search for different answers on the Internet. Some of them are patch problems, some are caused by not uninstalling the. net framework, some are caused by registry IE browser permissions, and some are folder files without permissions...

I tried to install cleanup_tool.exe in multiple regions. The Registry and folder permissions cannot be modified, and the patches cannot be uninstalled. 4.0. It took a day to crash. Later, I found a method on the Internet and checked the log.

In fact, it is very easy to solve the Windows Installer installation error 1603. Find the corresponding Installation log File, locate the first few lines of return value 3, locate the error, solve the problem, and then reinstall, OK.

Check that the core dll files under C: \ WINDOWS \ Microsoft. NET \ Framework \ v2.0.50727 \ are occupied, so they cannot be read and written. The solution is as follows:

1. Stop WWW Service

2. Stop all SQL database services

3. Stop self-built. NET application services (server programs written in. net by yourself). It is to stop all services that. net can use.

Try again and find that it is useless. the culprit is 360 anti-virus software !!!!

Close and then install it .... No harm... Uninstalled directly
