Run-time Error 339 - 'CRYSTL32.OCX or one of its dependencies are missing or invalid' occurs in QuickSell 2000.
Check to make sure you have the crystl32.ocx, crpe32.dll and stdole32.tlb files on your hard drive. These files are typically found in the C:\Windows\System or C:\Windows\System32 folder. If you don’t have these files, copy them from a working workstation.
In one case after installing Norton Systems Works 2003 the files were missing and once they were replaced the error subsided.
