Information in this support solution applies to: C51 Version 6.00 I receive the following error when I link a very simple project in the EVAL version: FATAL ERROR L213:I/O ERROR ON WORK FILE: EXCEPTION 0029H: ACCESS TO FILE DENIED I've checked all the Environment Setup settings (TOOLS.INI or BIN/INC/LIB Folder) and everything seems OK. The autoexec.bat file settings: SET TEMP=C:\WINDOWS\TEMP SET TMP=C:\WINDOWS\TEMP Why am I receiving this error message?
One more possible reason that happened to a colleague of mine, though with the actual output instead of the "work file": If there's a subdirectory in the target directory (temp, here) that happens to have the same name as what the compiler is trying to create, you'll also get a permission violation error.
