Installation of Garmin Express 3.2.x and higher fails on CPU's without SSE2 support

Former Member over 11 years ago

Hi

I was helping a friend to install Garmin Express for the use of the GPSmap 64s (I recommanded this device, cause I have the same and I am quite satisfied with).

Unfortenatly the installation of the latest version 3.2.9 fails. To be more exact: the Garmin Core Update Service. The start of this service procduces the error code 0xC000001D.

I had a deeper look at the error code 0xC000001D, which means "illegal instruction" and appears often on older PC with CPU's like the Athlon XP that don't have SSE2 on board. He has a PC with an AMD Athlon XP 3200+ which does not have SSE2, only SSE.

After some tests, it looks like the DLL which needs SSE2 seems to be the "XercesLib.DLL" from the Apache Software Foundation:
http://xerces.apache.org/xerces-c/
Since version 3.1.0 the performance has been improved using SSE2 instructions and the Garmin Core Updater Service comes with version 3.1.1.

Two DLL's from the Garmin Core Update Service are importing the "XercesLib.DLL":
"legacyio.dll" and "XMLdll.dll"

Could Garmin developpers be so kind to rebuild these DLL's with the older version 3.0.1 of "XercesLib.DLL" or build a new "XercesLib.DLL" version 3.1.1 without the option __SSE2__ in the preprocessor definitions and without "Enable Enhanced Instruction Set". Thanks.

Or any other developper reading this with Microsoft Visual Studio 2013 (seems to me compiled with this version) at home. The source code is availabe from the link above. Thanks in advance. Just one DLL to replace and there is no need for another PC.

BTW:
Maybe the DLL "legacyio.dll" from Garmin is also using SSE2 instructions. I didn't search for SSE2 opcodes in the DLL so far, but it's quite possible, because SSE2 instructions are the default instructions on x86 platforms when using Microsoft Visual Studio 2012 or 2013. Dont know for 2010.

I am still sure that the missing SSE2 feature in the AMD Athlon XP causes the problem. Or is there anybody out there using Garmin Express 3.2.9 with such a CPU? Or another CPU without SSE2.

Garmin does not indicate in the system requirements for Garmin Express, that a CPU with SSE2 is required. The developpers from Garmin should check this out. SSE is enough for a update service.

This thread relates to my thread : https://forums.garmin.com/showthread.php?93274-Express-3-2-7-0-will-not-install-on-Win7-32bit-legacyio-dll-won-t-load

Please could support comment on this and pass the information to the developers. This is something that is fixable with compiler flag changes and would extend the life of otherwise perfectly fine PCs.

Keeping this alive and on the front page.

It's about time customer support at least acknowledged this thread.

The information has been submitted and our software developers are looking into this.

Thank you for the post.

Any news here?

I am sorry to inform you that we are unable to offer support on the older CPUs, that are not SSE2, such as Athlon XP 3000+ and Athlon XP 3200. These CPUs were delivered in computers back in 2003 and are unfortunately outdated. My suggestion is to use a computer with newer technology in order to be able to utilize our free software.
