I just installed 4.0.2 on a brand new Win2003 Server with SQL 2005 and VS 2005. No problems there.

However, when running the install.aspx page I got a permissions error. Fixed the permissions but the code was throwing an exception in the config classes where the following code is:

Dim xmlMachineKey As XmlNode = xmlConfig.SelectSingleNode("configuration/system.web/machineKey")

xmlMachineKey.Attributes("validationKey").InnerText = validationKey

xmlMachineKey.Attributes("decryptionKey").InnerText = decryptionKey

xmlConfig = AddAppSetting(xmlConfig, "InstallationDate", Date.Today.ToShortDateString)

I commented out the xmlMachineKey attribute setting portion to get it working... however, I'm not sure why this exceptioned out...

Any ideas?

The exception is actually an Object Not Found... in other words, xmlMachineKey was "Nothing" after it's init (SelectSingleNode). The proper section does exist in the web.config.

I'd love to hear what anyone might think of this.

hi

i have exactly the same problem and found no help. i installed dotnetnuke 4 with vs.net 2005 and sql server 2005. i also reloaded msxml 6.0 parser with no sucess:(((

web.config was loaded in xmlconfig variable as xmldocument but the method .selectsinglenode will always return nothing. i tested with other xpath-query but i always get nothing! so xmlMachineKey.Attributes("validationKey").InnerText = validationKey will fire a "object not reference to an instance of an object"-error:( my apppool-identity for asp.net 2.0 is in administrator-group. so it could not depend on a permission problem.

can anybody help me? thank you so much!

greetings,
dave
