While trying to test solutions to Sytze's question, I wanted to use Filer to locate some files, and got an error 1733 when trying to run the program:
DO form HOME(6)+"filer\filer"
When you try to execute the find, it reports that Filer.dll is not registered, and offers to do this for you. It then reports failure, Error 1733, method find, line 42, Class definition FILER.FILEUTIL is not found. Here's the trick:
Locate the two VC runtime DLLs MSVCR71.DLL and MSVCP711.DLL
Start a command prompt with Administrator access and navigate to the Filer directory
Issue:
regsvr32 filer.dll
and you should get a success message. If it fails or things go funky, try:
regsvr32 /r filer.dll
to un-register the COM DLL and you can try again.
Hat tip to the Fox Wiki at http://fox.wikis.com/wc.dll?Wiki~Filer~WIN_COM_API for the clue!
