 Possible causes:
 
 - The precompiled header was compiled with a previous compiler version. Try recompiling the header with the current compiler.

 # Fatal Error C1854
 
 > cannot overwrite information formed during creation of the precompiled header in object file: '*filename*'
 
+## Remarks
+
 You specified the [/Yu (Use Precompiled Header File)](../../build/reference/yu-use-precompiled-header-file.md) option after specifying the [/Yc (Create Precompiled Header File)](../../build/reference/yc-create-precompiled-header-file.md) option for the same file.
 
 To fix this issue, in general, set only one file in your project to be compiled by using the **/Yc** option, and set all other files to compile by using the **/Yu** option. For details on the use of the **/Yc** option, and how to set it in the Visual Studio IDE, see [/Yc (Create Precompiled Header File)](../../build/reference/yc-create-precompiled-header-file.md). For more information on using precompiled headers, see [Creating Precompiled Header Files](../../build/creating-precompiled-header-files.md).

 # Fatal Error C1900
 
 > Il mismatch between '*tool1*' version '*number1*' and '*tool2*' version '*number2*'
 
+## Remarks
+
 Tools run in various passes of the compiler do not match. *number1* and *number2* refer to the dates on the files. For example, in pass 1, the compiler front end runs (c1.dll) and in pass 2, the compiler back end runs (c2.dll). The dates on the files must match.
 
 To fix this issue, make sure that all updates have been applied to Visual Studio. If the problem persists, use **Programs and Features** in the Windows Control Panel to repair or reinstall Visual Studio.

 # Fatal Error C1902
 
-program database manager mismatch; please check your installation
+> program database manager mismatch; please check your installation
+
+## Remarks
 
 A program database file (.pdb) was created using a newer version of mspdb*XXX*.dll than the one the compiler found on your system. This error usually indicates that mspdbsrv.exe or mspdbcore.dll are missing or have different versions than mspdb*XXX*.dll. (The *XXX* placeholder in the mspdb*XXX*.dll file name changes with each product release. For example, in Visual Studio 2015, the file name is mspdb140.dll.)

 # Fatal Error C1905
 
-Front end and back end not compatible (must target same processor)
+> Front end and back end not compatible (must target same processor)
+
+## Remarks
 
 This error occurs when a .obj file is generated by a compiler front end (C1.dll) that targets one processor, such as x86, ARM, or x64, but is being read by a back end (C2.dll) that targets a different processor.
