Hello,

    We are seeing a serious deployment issue with 8.3 and 8.3 hotfix. When we run the latest version of our Winform application on our test machines the application will not start due to "system.io.filenotfoundexception".

Using dependency walker on various test machines we are finding differing missing files, but mainly GDIPLUS.dll and DWMAPI.DLL.

We do not reference these items directly anywhere in our application.

Following various threads around the topic we are seeing a lot of noise which suggests 3rd party components having direct references to IE7 dlls and other versions of dlls which are only found on WIndows Vista machines, not XP SP2 machines like we are using.

Could this be an issue with V8.3 of Infragistics for Windows?

If you do not could I suggest ... it could be ?

Thanks

Hi,

I've successfully installed the Infra HotFix 8.3 of december (8.3.20083.2021) without any problems, on test PCs and on customer's PC.

Do you have verified in VS project that the Property "Specific Version" of all Infra DLL referenced in the project is set to FALSE?
If this prop is true you can get the issue "file not found" because .Net try to locate the previous version of DLLs (specified in the VS project), that there is not.

I hope this help.

You're welcome,

For your information, I dont install on test and client machine the Infragistics (or any third part DLLs) in the GAC, I put the DLLs in the same folder of application. This it's better if you frequently update your apps.

This work also in network evrionement, with apps & DLLs in a shared folder on the server. You need only to setup the .Net config files in the client PC and put the shared folder path (or root server path) in the right security area of the PC (via Options-Secuirty in Internet Explorer).

Have a nice week,
Davide

Hello Davide,

    Thank you for your top tip!

    This attribute wasn't set on the bulk of our Infragistics references BUT it was set on the Infragistics2.Excel.v8.3.dll and the Infragistics.Win.AppStylistSupport.v8.3.dll references, which I am now changing.

We believe the problem we are seeing may be to do with the installation of the hotfix on the test servers. We have our WinForm application deployed on a terminal server which we then connect to. The Infragistics assemblies seemed to be installed correctly in the GAC but when we double checked this by put the assemblies in the application folder, the application now works!

At this stage we are uncertain as to the root issue - whether it is security, the issue you pointed out to us or a bad install, but I will let you know if we get a definite answer.

Thanks for your help.
