This behavior may occur, if you revert your web- or conversion server to an erlier version of Fabasoft Folio.

fscvext.dll is the ISAPI module responsible to redirect web request to the Fabasoft Kernel.

Fabasoft registers it's ISAPI module fscvext.dll in IIS. If the uninstallation misses removing the modules entries, it may fail to start an older version of Fabasoft Folio.
