ActiveX cleanup utility (uacflchk)
The Campaign ActiveX cleanup utility, uacflchk.exe, is designed to resolve Object not Loaded / Object does not support this property or method errors when a user tries to access Campaign pages with ActiveX controls. This problem most often occurs when the files needed to run ActiveX are not downloaded to the Windows Downloaded Program Files directory.
The utility runs in two modes: check and clean. You should run the utility in check mode first, to ensure that you take any necessary action before running the tool in clean mode.
The uacflchk.exe file is located in the tools\win32 directory under your Campaign installation.
