# Latex Error: File scrlayer-scrpage.sty' not found

I have a Latex form for my PhD thesis presentation. When I run it, the latex shows this error: Latex Error: File scrlayer-scrpage.sty' not found. I was wondering if someone could help me about my problem. This is something written in my Latex:

• How did you install LaTeX? – Joseph Wright Apr 30 at 16:54
• is your tex system a current system? – Ulrike Fischer Apr 30 at 16:55
• @JosephWright I downloaded the LaTeX from a cite and installed it. – M.Ramana Apr 30 at 16:57
• @JosephWright I downloaded the LaTeX from a cite and installed it. – M.Ramana Apr 30 at 16:57

There an "invisible" character for the TeX editor (using TeXstudio) all over the code that prevents its correct compilation.

I opened the tex file with notepad++ > View >Show Symbol > Show All Characters

to see for example

â€Ž\addbibresource{example.bib} % The filename of the bibliographyâ€Ž

The first â€ž is a UTF-8 character that should not be there!

U+201E 0x84 „ â€ž %E2 %80 %9E

After cleaning the file (again with notepad++) it compiles without errors.

This is the cleaned code

Update

I can only reproduce the error ! LaTeX Error: File scrlayer-scrpagex.sty not found. by changing the line 278 of the file MastersDoctoralThesis.cls from \RequirePackage[markcase=used]{scrlayer-scrpage} to, for example, \RequirePackage[markcase=used]{scrlayer-scrpagex}.

My guess is the file you are using is somehow corrupted. Get a new one from https://www.latextemplates.com/templates/theses/1/thesis_1.zip

• Thank you very much for your help. I used the cleaned code but unfortunately it doesn't work yet because of "Latex Error: File `scrlayer-scrpage.sty' not found". – M.Ramana May 1 at 2:37
