Recently we deployed a batch of new Windows 7 x64 PCs for our new operation. A few of them need to access our legacy Transport Management System. The legacy TMS is mostly working fine in IE 10, except for few report pages.
For some reason the report didn’t load. Internet Explorer barfed the following error windows.
I guess it is really a moment of “If I don’t blogged it, I surely forgot it”™.
Anyway, to solve this problem we need to open Internet Explorer’s Advanced Options. Under Security, you need to untick the “Allow software to run or install even if the signature is invalid”.
After installing the Crystal Report ActiveX control, please tick back this option to prevent you from installing malicious ActiveX from Internet.
I hope it helps, cheers!
