Vista 64bit - Arithmetic operation resulted in an overflow

Nov 6, 2009 at 9:07 PM

I have been using OpenNetCF for about 3 - 4 years now and it is a very stable product.

Lately I have heard of customers having problems with Vista 64bit OS. The following exception is thrown:

Arithmetic operation resulted in an overflow


Has anyone else run into this? Is there a fix for this?

Do you use the latest source code or the download version?

No I am using a 3 year old version. I'll download the latest version and try. Darn I can't seem to find the download for the DLL. Do I have to download the source and build it myself?

I downloaded the 27109 source code and built it and tested it on a Vista 64bit machine. It seems to be working. Got to do a little more testing to make sure it still works on XP and Vista 32bit.

The old DLL I had was from 2007

27109 should be fine with x86 and x64.
