Well I have read through all the post concerning WB5, still can not get mine to work, I have all the problems. I looked for the activate.exe file, don't have that file anywhere on my computer. WB4.6 works get, SDC has the WB5 sometimes it installs, but won't activate, sometimes in installs half way then SDC just closes and doesn't install, one time it said it was WB%, but WB4 was still there when I openned it, it worked, but wasn't WB5. I have installed/re-installed/uninstalled about a dozen time in every concievable order, no dice.
