I installed Miktex and after restart Texstudio.
Unfortunately I get this two error messages after starting Texstudio and I don't have much idea about

1. The procedure ...point.... has not been found in DLL"C:\Program...\pdflatex.exe"
2. The procedure...point "??ReportingLine@Application...point.... has not been found in DLL"C:\Program...\MikTeX209-pdftex.dll"
.exe"
3. 1. The procedure ...point. "?WideCharToUTF8... has not been found in DLL"C:\Program...\kpsewhich.exe"
Sorry, I don't get a complete log of this.
