+# Fatal Error C1090
+
+> PDB API call failed, error code '*error-number*': *message*
+
+An error occurred in processing a PDB file.
+
+Error C1090 is a catch-all for uncommon compiler PDB file errors that aren't reported separately. We only have generic advice for resolving this issue:
+
+- Do a clean operation in your build directories, and then do a full build of your solution.
+
+- Reboot your computer, or check for stray or unresponsive mspdbsrv.exe processes and kill them in TaskManager.
+
+- Turn off antivirus checks in your project directories.
+
+- Use the [`/Zf`](../../build/reference/zf.md) compiler option if using [`/MP`](../../build/reference/mp-build-with-multiple-processes.md) with MSBuild or another parallel build process.
+
+- Try building by using the 64-bit hosted toolset.
+
+For more troubleshooting or workaround information, search for this error on [Developer Community](https://aka.ms/vsfeedback/browsecpp) or [Stack Overflow](https://stackoverflow.com/search?q=C1090).
+
+You can also report the issue on Developer Community. For more information, see [How to report a problem with the Microsoft C++ toolset](../../overview/how-to-report-a-problem-with-the-visual-cpp-toolset.md).
