Error: 'Unable to create an instance of required object: fileproxy'

Issue

---

After uninstalling Macromedia Homesite, Windows Explorer presents the error "Unable to create an instance of required object: fileproxy" when it is started.

Reason

---

This issue occurs if DLL files that are installed with HomeSite are not entirely removed from your system after uninstalling HomeSite.

Solution

---

1. Open the System folder (C:\windows\system32) and look for the following DLLs:
   • cfvalidator.dll
   • CFSourceControl.ocx
   • CfShellFtpRds.dll
   • CFFileProxy.dll
   • CFFtp.dll
   • CFRegExp.dll
   • cfssvradmin.dll
   • wddx_com.dll,
   • xmlparse.dll
   • xmltok.dll
   • cfmsg.dll
   • cfrds.dll
   • CFSDebug.dll.
   Ordinarily, if all Macromedia HomeSite/Studio installations have been entirely uninstalled, these files will not be there. However, if some or all of them are there (whether or not other HomeSite/Studio installations exist), unregister and delete them.
2. To unregister them, open the command window (Start > Run> CMD) and use the following commands:
   
   regsvr32.exe /u CfShellFtpRds.dll
   regsvr32.exe /u CFFileProxy.dll
   regsvr32.exe /u cfssvradmin.dll
   regsvr32.exe /u cfvalidator.dll
   regsvr32.exe /u CFSourceControl.ocx
   regsvr32.exe /u CFRegExp.dll
   regsvr32.exe /u wddx_com.dll
   regsvr32.exe /u cfrds.dll
   regsvr32.exe /u CFFtp.dll
   regsvr32.exe /u circ3.ocx
   regsvr32.exe /u CFSDebug.dll
