Answers Database Design Manager: System Error, Unhandled Exception: ERROR_FILE_NOT_FOUND Record #1151 Product Family: Software Product Line: M1 Graphical/General Product Part: Design Manager Product Version: 6.0.1 Problem Title: Design Manager: System Error, Unhandled Exception: ERROR_FILE_NOT_FOUND Problem Description: In case Solution Record 752 did not work. When invoking the design Manager this error occurs: OSErrorHolder class >> reportOn: OSErrorHolder >> reportError [ ] optimized System Error >> handleError For: FATFilename (Filename) >> isDirectory Solution 1: This error occurs if you delete a version of a project you created outside of Design Manager. If yo u need to delete a version do it under Design Manager, the delete command is under the Design menu. This solution will not let you get back previous Versions of the design, you will have to Translate & Implement the design again. Solution: Quit the Design Manager. In your working directory there should be two files one named de sign.bak and another named design.prj. 1) Close the Design Manager. Get into your file manager/explorer. 2) Delete the .bak file 3) Erase everything in the .prj file (you might need a carriage return or space in the file in order   to save it that is okay) so you should now just have a design.prj that is a couple of bytes big. 4) Start up the design manager. It should prompt you with this message>> Cannot read the project file: c:\xxx\xxxx\design.prj. The file is unreadable and may be corrup ted. Do you want to recover, using the project backup file? Answer with a Yes. Next Message>> Could not recover using the project backup file. Do you want to recreate the project information? Answer with a Yes. 5) Now a New Project screen will pop up and you will need to specify your top_level_design.1     This is where some problems occur. It may or may not let you choose a Target Family.     (a)If it does choose the one you want, and everthing else should be okay (you should be able to t ranslate).     (b)If it doesn't let you choose it will give you this error >>         Cannot find data file ".bos" in the XACT path.         If you get this press cancel.         Then go to File -> New Project and specify your top_level_design.1 file         You should now be able to translate and continue from there.
