Have seen this too. Another place to look is Windows Updates for this particular issue. Can't give specific one(s), but have had applying all available resolve twice. Have also seen C++ be an issue. In one case had to uninstall, but could not get reinstalled... kept giving permissions error. Traced where installer was extracting another file to temp folder, copied that file out of temp and ran as administrator from another location. Worked. Even changing to Everyone = Full Control on temp did not. Go figure.
