Issue
When you start AutoCAD® or AutoCAD LT® software, the following error message is displayed:
Error starting program, msvcp60.dll is linked to missing export msvcrt.dll:_lc_collate_cp. Device attached to system is not functioning.
Solution
The problem occurs if you have installed an older version of CorelDRAW®, WordPerfect®, or Bryce®. The installer for these Corel products replaces the msvcrt.dll file with an older version, thus breaking links to msvcp60.dll and possibly other dynamic link library shared support files.
To resolve this problem, uninstall and then reinstall AutoCAD or AutoCAD LT. The Corel product that you have installed will not be adversely affected.
