I had similar problems recently, with IE7 and IE8 only (with MVC4).

To get validation working again, I have the following versions installed:

jQuery: 1.8.3

jQuery Validation: 1.9.0.1

Microsoft Unobtrusive Validation: 2.0.30116.0 (latest as of May 14, 2013)

I noticed that moving to jQuery Validation v1.10 was where the problems began. At the time of this post JQuery Validation is v1.11.1 and does not work in IE7/8. This was also tried with both jQuery 1.8.3 and 1.9.1, neither worked with the latest version of jQuery Validation.

Note: The particular problem for me was validation was firing and flagging error for all inputs and checkboxes even if they were not 'data-required'.
