I compiled a .tex file in TeXworks for Windows 7 that had a graph in it, so I had to install the TikZ library for LateX.
Afterwards, all compilations are failing. The TeXworks console displays
texify.exe: Permission denied: myFile.log texify.exe: Data: myFile.log
Strangely, I do not have the pdf document open in other programs such as Adobe Acrobat. I tried closing and reopening TeXworks to no avail.
How can I grant TeXworks permission to compile my .tex file?
