# Error in TeXstudio with unicode-data package

I am struggling with this error:

Unfortunately, the package unicode-data could not be installed. Please check the log file: C:/Users/G/AppData/Local/MiKTeX/2.9/miktex/log/pdflatex.log

Error: Command crashed: pdflatex.exe -synctex=1 -interaction=nonstopmode "icml_paper".tex

The MiKTeX Package Manager tries to install a package but fails, otherwise the compilation goes through and I can see the resulting PDF document, which looks fine.

This happens every time I am compiling a ".tex" file with `asymptote` drawing in the document. But it seems as though it is not directly related to `asymptote` (since compiling `asymptote` drawing by running `asym`, works fine).

I get the following log message in `pdflatex.log`:

I tried to install the package `unicode-data` from the CTAN site, this didn't solve the problem.

Any help or suggestions would be very much welcome.

RESOLVED: The problem was that the package was just not in my local package repository (never happened before). In fact, the package was not listed in the MiKTeX Package Manager, so I had installed it manually, which didn't help (I might not have installed it properly after all) after "Changing Package Repository" in MiKTeX Package Manager to the internet based repository, the package did appear in the listing and installing it solved the problem.

• Try to install (preferably as Admin) from MiKTeX Package Manager, while compilation has ceased. Dec 16, 2016 at 21:24
• For some reason (which might be very much related to the error) I can not find unicode-data package in MiXTeX package manager (there is, however, package called unicode-math). The package does appear in the link ftp.math.purdue.edu/mirrors/ctan.org/systems/win32/miktex/tm/…, so I have installed it manually, is there a way to point MiXTeX Pkg. Manager to this link?

• I have it. Synchronize the contents of the repositories (menu `Repository -> Synchronize ` in MPM 'Admin), then install. Dec 16, 2016 at 22:21
• @them could you answer your own question and mark it as solved?

Some details: MiKTeX Package Manager was configured to use a local repository on my PC, which I downloaded with the installation of TeXstudio, the `unicode-data` package was not in my local package repository, this never happened before with any other package, and the error didn't clearly reflect what was the problem.
