evo iz Help file-a jednog programskog jezika:
When running oleview.exe, some systems will complain about a missing file called iviewers.dll. This file is required, but strangely enough not included in the latest setup. You can obtain this dll from an older version of oleview.exe at: http://download.microsoft.com/download/2/f/1/2f15a59b-6cd7-467b-8ff2-f162c3932235/ovi386.exe. It will install the files by default to the C:\MSTOOLS\BIN directory. You only need the file iviewer.dll. Copy it to the same directory where oleview.exe resides, then register the dll using the command line: regsvr32 iviewers.dll.
