The server upgraded the system patch  and found that all. NET Web sites could not be opened, prompting "


the request could not be executed because the application domain could not be created. Error: The 0x80070002 system cannot find the file specified. ", but PHP and ASP are normal, so make sure the. NET Framework is broken.








Search online answers are different, some of them are patches, some are not uninstalled clean. NET Framework caused, some are registry IE browser does not have permissions, some are folder files do not have permissions ...






Tried a lot of methods, such as Cleanup_tool.exe completely clear or not installed. Modify the registry and folder permissions, etc. also can not be installed, the patch is not installed all uninstall. 4.0 can be installed properly. Got a day to rush into the crash. Later on the web found a way to view the log.






In fact, troubleshooting Windows Installer installation Error 1603 is simple, find the appropriate installation log file, locate the first few lines of return value 3, find the error, resolve the problem, and then reinstall, OK.






After viewing the DLL files found to be C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\ below the core is occupied, so cannot read, write. So the workaround is as follows






1. Stop WWW Service



2. Stop all SQL database services



3, stop self-built. NET App service (your own. NET-written server program) anyway, stop everything. NET services available










Close and then install it all went well .... Hairenbujian Ah ... Uninstalled directly.
