How can I manually install a package on MiKTeX (Windows)
I recently installed MiKTeX 2.9 and also installed a .cls-file. I did this by copying the .cls-file to the directory "C:\Program Files (x86)\MiKTeX 2.9\tex\latex\sim\simauth.cls" and ran Refresh FNDB + Update Formats in MiKTeK Options (Admin). This worked perfectly, and my documents compiled just fine.
This .cls turned out to be an old version, and so I found the newest version of the .cls-file (also called simauth.cls). I just copied this .cls-file to the same directory and the old .cls-file was overwritten. Again I ran Refresh FNDB + Update Formats, but when I compile, the documentclass has not been updated. I also tried deleting the .cls, but I were still able to compile perfectly.
The .cls-file in question is this, and it is because of the update-date, \def\update{2010/03/10 v3.00}, that I am sure the .cls has not been updated properly.
Any help is much appreciated, thanks.
C:\whateveryouwant\tex\latex\sim. Move the cls to the sim folder. And then addC:\whateveryouwantas a new local root in miktex-settings. – Ulrike Fischer Nov 20 '12 at 13:15
