Q: I just installed a software for many times, what is annoying is that: I come across the error message "This application failed to start because DNSAPI.DLL was not found. Re-installing the application may fix this problem." I've downloaded the DNSAPI.DLL zip file I need from internet. It didn't work! I don't know if I have done the right thing. How should I do? Many Thanks. Nelson
A: The answer is absolutely yes. Here offers you some advices of how to fix DNSAPI.DLL missing errors.
At whiles, a newly installed program might be the main reasion of DNSAPI.DLL missing error. Before you uninstall the software, you had better perform a totally clean for your computer.

2. Click Start, type msconfig.exe in the Start Search box, and then press Enter to start the System Configuration utility.

4. On the Services tab, click to select the Hide all Microsoft services check box, and then click Disable all.
Note This step lets Microsoft services continue to run. These services include Networking, Plug and Play, Event Logging, Error Reporting, and other services. If you disable these services, you may permanently delete all restore points. Do not do this if you want to use the System Restore utility together with existing restore points.
