error on including Infragistic controls in webclient assembl

Dear all,

When I am trying to include Adv GUI controls in webclient application assembler, prowcapp file is generated successfully, but when opening it on webclient deployment packager, this error is shown -

WebClient Deployment Packager

Unable to open D:\-\\.prowcapp.The prowcapp file you are trying to open uses a format that this version of the tool does not recognize.

OK

Pl suggest remedy for this error.

If I do not include Adv Gui controls, everything is working fine.

Thanks
