Re-install problem

[pitaridis]

When I install a copy of my application and then I try to reinstall the application or an earlier version, the OS displaying a message in order to inform me that it is not possible. Does anyone know how to solve this problem????

You may need to un-install the application using the control panel

add-remove ??

 

[pitaridis]

I know that I have to uninstall it. Is there any way to avoid it so that the installation program will make all tha changes to the system in order to automate the whole procedure???

Why is it not possible? What does the message say is wrong?

See Clickonce

pitaridis, in ClickOnce you can increment your Application Assembly version and the application is updated with the newer version. If you contradictory to your stated Primary Platform does not use .Net 2.0 (then update it!) and use a .Net 1 Setup Project you can set its RemovePreviousVersions property to True.

RemovePreviousVersions property to True but when I try to install a new version (I increased Major, Minor and build version) a message appears on the screen saying that there is an other version of this product and I have to uninstall it in order to proceed.

What is ClickOnce??

I have installed Visual Studio 2005 Professional edition.
