I installed QGIS 2.18 after i had uninstalled the version 2.16. It installed quite well but it is not starting at all. I went into the program directory and click on the exe file and got the error "The program can't start because qgis_app.dll is missing from your computer. Try reinstalling the program to fix this problem". I have installed severally and the same error keeps coming on. Any help?

I've had the same problem (missing dll files) with QGIS 2.14 LTR and I reinstalled several times. Opening QGIS with the bat file did not work.
My problem has been solved by uninstalling and searching for all "qgis" files (not the project files) on the C-drive and delete them (also temporary files).
After that and a fresh install of QGIS 2.14 LTR, it works!
