I downloaded 3 versions and those events happened.
1) VWG_SDK_6.3.6_NET3.5.msi
* In designer it says : Designer is not available in community SDK. In 6.2.4 there is no such a message.
* trackbar is not running correctly again. I have cleared the cache and delete the dll s from system\microsoft.net and incremented the private version number
2 ) VWG_Express_Studio_6.3.6_NET3.5.msi
*Designer is not available again, Visual Webgui Expression edition requires visual web developer 2008 express edition
I have visual web developer 2008 express edition. but designer not works.
* trackbar is not running correctly again.
3 ) VWG_Professional_Studio_6.3.6_NET3.5.msi (30 day trial)
* Designer is available now with this version will be expired in 29 days.
* trackbar is not running correctly again.
I have visual studio 2008 version 9.0.30729.1 SP and .net framework 3.5 SP1 and Silverlight 3.0 beta runtime and tools
and web developer 2008 express edition.
Because being a free user, i use the last stable version Setup_SDK_Net3.5_6.2.4.msi.
Thanks for all help.
