Hello Murad,

May I ask what product is this about? Thank you in advance.

Please be sure that you are logged in at https://www.infragistics.com/login.aspx, if so a welcome message accompanied with your email should be displayed on top of the page. Once you are logged in, click on the Account shortcut, in order to navigate to your keys and downloads. When the page is loaded, click on the product name you are interested in. Additional menu will be loaded on the same page [ Products & Bundles | Documentation & Samples | Source Code | Service Releases ]. As Boris directed you, the tab you should open is Service Releases. I believe you are looking for the Windows Forms release, since the last one is (.2111)

If you need any further assistance on this issue, or we (me and Boris) are missing something, do not hesitate to post in this thread.

It seems that the key you are trying the register is corporate and the maximum number of registrations is exceeded. In order to get further assistance please contact Infragistics registrations at registrations@infragistics.com

I am waiting for your feedback.

I send email to registrations@infragistics.com
