I am using a VB6 application packaged with Wise and installed in customer machines. Recently in 1 or 2 machines I noticed getting "Automation Error -2147217406" when try to open the EXE (Installation went fine without problems) also checked if the machine has missed any updates. In approximately 50 machines it worked fine; only 2 machines had this problem. I checked the windows events (under computer management->system tools ) when this error is throw but no event is captured and also I have application log which turned out to be 0KB. Now all the areas where I can troubleshoot is been shut down. Please advice what could be this problem. Thanks for your help in advance.
