HI Ivan, 

As you told , i downloaded the and installed the free trial. Then after new dlls came in to GAC. From there I used required dll and after some tweaking my one project build was successful and design view is getting open without error. So i think , with these dll may resolve my issues. 

We have around  18 applications (modules)  out of this 10  where infragistics tools are used. So to test the any module (after migration to VS2019)  is difficult. i can not test because other modules are still in VS2003. So to test applications by running i will have to migrate all application to VS2019 because dll those are build in VS 2019 is not compatible with VS2003.  However as i tested dll build in VS2008 are compatible with VS2003. and i can add reference of VS2008 dll into VS2003 application buit can not add dll of VS2019 app. So i wanted to test couple of module by migrating in VS2008. 

But when i try to to use newly downloaded/installed dll of infragistic in VS2008 it's not working. You can see in below screen with yellow warning in reference section.

So can you please confirm it is possible to use latest infragistics dll in VS2008 or not? if yes so what mistake i am doing? Please suggest.

Thanks.. Shailendra Singh

Hi Ivan,

Since i was still searching for installer and found two free version installer "UltraWebNavigator20MSFreeVersion" and "UltraWinTree20MSFreeVersion". After installation, Infragistics.License.dll is now in C:\Windows\Assembly. But there is no benefit of it. Design view still showing the error and infragistics controls are throwing error. The dll files those are used in application are different than found adter installation. 

However PublicKeyToken is same for free version installer dlls and dlls those are used in application.

What do you think above mentioned both free version installer can be useful or not? Please confirm.

You told to go to your account, then open “My Keys and Downloads” page. But there is no product under my account because this account is my personal and dlls are of my organization. So i will have to register there product  with  my id. But i don't have product key.

So can i use free version product key to register and then download platform installer and install?

Please confirm.

Thanks.. Shailendra Singh

Hi Ivan,

Thank you So much.

I Installed VS2008 to give one attempt. Project build is successful but in design mode  same all errors are coming as i showed in previous post's screen shot of VS2019.

GAC is not available under "C:\Windows\assembly". It's only under "C:\Windows\Microsoft.NET\assembly\"

but Infragistics.License.dll is not in any of above folders. and i don't have the setup/installer to reinstall. I checked at all possible places in my organization but could not found. So i am unable to reinstall this. Please suggest how can i reinstall and what should i do?

Thanks..Shailendra Singh

Hi Ivan,

Thank you so much.

licenses.licx is available under root location of project. I cleared the contents of file. All the right dll are in bin folder. 
After that rebuild was successful but when running the application it says "Visual studio has stopped the working" and VS gets closed automatically.

I also tried by excluding licx file from solution. After excluding the file clean/build/rebuild are successful but unable to run the application same error message "Visual studio has stopped the working" and VS gets closed automatically.

On design view below screen messages are coming.

Please review.

Thanks
