Hi, just install the shopping cart module. Our site is running on DNN 05.02.03. After successful installed of the module, it shows the error below when added module on the page.

Smith.BuyNow

Error: Smith.BuyNow is currently unavailable. DotNetNuke.Services.Exceptions.ModuleLoadException: (0): error CS1705: Assembly 'App_Web_productslist.ascx.54f2e0e1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'AjaxControlToolkit, Version=3.0.30930.28736, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' which has a higher version than referenced assembly 'AjaxControlToolkit, Version=1.0.20229.20821, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' ---> System.Web.HttpCompileException: (0): error CS1705: Assembly 'App_Web_productslist.ascx.54f2e0e1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'AjaxControlToolkit, Version=3.0.30930.28736, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' which has a higher version than referenced assembly 'AjaxControlToolkit, Version=1.0.20229.20821, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e' at System.Web.Compilation.AssemblyBuilder.Compile() at System.Web.Compilation.BuildProvidersCompiler.PerformBuild() at System.Web.Compilation.BuildManager.CompileWebFile(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResult(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.UI.TemplateControl.LoadControl(VirtualPath virtualPath) at System.Web.UI.TemplateControl.LoadControl(String virtualPath) at DotNetNuke.UI.ControlUtilities.LoadControl[T](TemplateControl containerControl, String ControlSrc) at DotNetNuke.UI.Modules.ModuleHost.LoadModuleControl() --- End of inner exception stack trace ---

Any solution for this error? Thanks.

Hi, thanks for the reply. I have tried add the script as below after /system.webserver on web config file.

<runtime>

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31BF3856AD364E35"/>

</dependentAssembly>

<assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31BF3856AD364E35"/>

</dependentAssembly>

</runtime>

But it still not helps. And I also checke on "Host-Host setting" our site is running .net framework 3.5. What am I missing from your instruction? Thanks.

Hi, I have done both replaced the productlist.ascx file and reinstalled shopping cart module with new productlist.ascx file replaced in. Looks like it isn't working. And When I click module "Settings" on the "Buy Now" module trying to change some settings, it can not save.

I do check the "event viewer", everytime when I reinstall shopping cart, although it indicated success installed. But plug with the error message below.

Thanks for any help.
