Previously used winXP operating system running normally (very good) when switching to win7 operating system, this error, read errors from the SQL Server data, what is the error ? http://www.mediafire.com/view/4q5ux6e66ds4avb/ErrorOpenSQL.jpg/file

Small world. An ancient app that I wrote in VB6 with a SQL connection is dead on 64 bit Windows.

Because the company wants to move to newer Windows after 15 years they contacted me and we are working on a new version.
I can't tell what your app is or does but sometimes you have to get back to the developer to fix or upgrade.
