Crash on XPsp3/2003 CefSharp v37+ (FileLoadException)

[Alexander Markov]

Hi, looks like CefSharp v37+ doesn't work on old systems (2003/xp)

Library CefSharp.Core couldn't be loaded.

check this thread on SO (exactly same problem)

https://www.google.ru/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB8QFjAA&url=http%3A%2F%2Fstackoverflow.com%2Fquestions%2F28106861%2Fcefsharp-on-windows-xp-vs-2010&ei=LbITVffhIcLXyQO4soGoBQ&usg=AFQjCNH-L_hATEiGMkTjRRHAEh6k-cOR9g&sig2=muCOPQUFQPBsyTO5B_kRcA&bvm=bv.89217033,d.bGQ&cad=rjt

these are screenshots of opening Cefsharp.Core.dll (ver 33 and 37) in XP SP3 (.net 4.0, redistributable 2012, big amount of updates installed)

33 works fine

37 doesn't

Can anybody investigate this bug further pls?

As stated in the FAQ we no longer support Windows XP see https://github.com/cefsharp/CefSharp/wiki/Frequently-asked-questions#9-windows-xp-support

There are reports of it working on Windows XP e.g. https://github.com/cefsharp/CefSharp/issues/708

Your best bet is to find someone who has successfully got it working.

(Nobody on the `CefSharp Team` has `Windows Xp/2003`, so there is little we can do).

If you have VS2013 and some time, you could try building from source with a minor modifications.

- Make sure you build in `Release` mode when deploying to XP/2003
- Change the two c++ projects `Platform Toolset` to `Visual Studio 2013 - Windows XP (v120_xp)`
- Make sure the machine your deploying to has `VC++ 2013 Redist` installed.

This is a long shot......

Thx, it works even with 2012 (v110_xp)

But are there any chances to get packages for xp via nuget in the future?

Changing to the VC++ `XP` variation was enough to get it working?

The build script is there should you wish to generate your own `nuget` packages. Easy enough to publish to a custom `MyGet` feed.

yes

Thanks for the conformation, much appreciated.

Stupid question, but: Couldn't we make the default be to build using the XP compatibility settings (vs120_xp or vs110_xp) by default? Are there any specific reasons why we wouldn't want to do that?

I do think we are a few people that need XP/2003 support, so if it doesn't break anything else, I think this would be a more suitable default.

Best regards,

Per

Hi Alex,

Hi, Elmah

try to use newer version 39 https://www.nuget.org/packages/CefSharp.Common.XP/

there are some important updates related to memory leaks

if u can't, try to rebuld 37 version from sources with 'Platform Toolset' changed to Visual Studio 2012 - Windows XP (v110_xp)

Alex, 

I have used cefsharp V39 and  tried to test it on windows XP.

I have done some research to make it work for windows XP with .Net framework 4 client profile.

Following the given link I have installed a nugget for windows XP

https://www.nuget.org/packages/CefSharp.Common.XP/

Problem is It works fine on my local machine but when It comes to windows XP It does not work there and throw some exceptions.

Please suggest how to overcome this issue because I really need to get going further on this project.

[Alexander K.]

do you use WPF or WinForms? nuget package v39 for XP is only built for WPF
