This error often appears on windows running systems Installation Problems Problems with Fonts in Math Environment In this case steps 5-8 are sufficientĪnd can be carried out using the default Program Files location. The problem can arise even if you do not use a UNC path for the windows profile. If a directory for Lyx does not exist create a new one.
Cut these 4 files and paste them into the \\Username\Application Data\LyX folder. After the configuration has been finished you will find 4 files in the directory c:\ -> configure.log, faults, textclass.lst and packages.lst. 
Type "c:/lyx15/python/python.exe c:/lyx15/resources/configure.py" in the Command Prompt and press "return". Start the Command Prompt in windows (Start -> All Programs -> Accessories -> Command Prompt). Reinstall LyX and consider, that you use a folder whose name exists of just one word like C:\Lyx15. #LYX UPDATE PACKAGES PC#
Uninstall LyX from your PC if you have used an installation folder whose name exists of seperate words like C:\Program Files. One solution I have found is the following: This problem may come into existence if you use LyX on a windows-pc where your windows/application profile is not stored local but on an UNC path (i.e. LyX does not start and gives the error message: unable to find textclass file Unable to find textclass file (Windows). Tested with Lyx 2.0 and MikTeX 2.8 under Windows 7.Lyx has been closed because of an unexpected situation. That’s it! When you start a new document in Lyx, your new class should appear within the drop-down box for Document Class in the Document Settings window ( Document > Settings). Restart the Lyx program when it prompts you to do so. Open Lyx, and click Tools > Reconfigure. Open up your new layout file, and look at the second line. Rename the file to match your class name, say, “newclass.layout” For example, if our new Latex class is a template for an article, we might want to start by copying article.layout from C:\Program Files (x86)\LyX20\Resources\layouts and pasting it into C:\Users\ UserName\AppData\Roaming\LyX2.0\layouts. It is helpful to start by just modifying an existing layout file which is similar in purpose to the Latex class we are trying to add. More importantly, the layout file points to the Latex class for generating the final output. #LYX UPDATE PACKAGES HOW TO#
This file contains instructions on how to roughly format a document when displayed within the Lyx program itself.
Next we need to create a layout file for Lyx to work with. When the black command line window displays, type texhash and hit Enter. Update the MikTeX list of classes by clicking the Windows Start button and typing cmd into the search box. Remember to replace UserName with your own Windows user name. 
Copy the new Latex class file “newclass.cls” into the MikTeX directory within your user settings folder like so: C:\Users\ UserName\AppData\Roaming\MiKTeX\2.8\tex\latex\ newclass\ newclass.cls. Let’s say we have a custom new Latex class called “newclass.cls” which we want to be able to use with Lyx under Windows.
