We have an Excel add in (PI-SDK developed) that's been working nicely on a 32 bit Win7. Some machines have PI-SDK 1.3.6 and a couple machines with SDK 1.4.
When one of the machines with SDK 1.3.6 was upgraded to 64 bit, we've noticed some parts doesn't work - specifically anything to do with the PISDKDlg.dll. I saw this thread (http://vcampus.osisoft.com/discussion_hall/development_with_osisoft_sdks/f/8/p/1918/9997.aspx) that seems like what I'm experiencing. I've compiled the app to specifically target x86 platform to no avail.
Is there anything else that I could try?
PS. We are currently running Excel 2007.
