Hi could someone please help,

Ive deployed my application to my webserver using the clickonce installation within Vb.

1 .When I goto the website i can install no probs

2. My mate can go to the website and install no probs

3. But a select few when they click on the install button, it will display a xml file rather then downloading.

Could someone please explain the reasons for this?

make sure they have the .NET Framework installed on their machine.

Thread moved to the appropriate forum

Find out if they have .net frame work 2.0 and if they don't have ask them to install .net 2.0 and try again. The second issue could be their .application association in the file association or you can look at the registry and make sure it is associated with application deployment.

Thrid, someothers also have the same issue and look at the following thread, there we are discussing about the same issue.

Collectively we can resolve it or we can ask someone from MS to help us resolve it :)

I believe there is a dependency on the browser version.

Though I can't find this anywhere - I just looked. Possibly IE.5.5.

Clearly the application manifest is opening in its raw format as XML and is therefore not being handled by the browser.

This has nothing to do with the availability of the .net framework as it can be installed as part of your installation.
