how to uninstall the ClickOnce application on install

Postby HonzaF » Tue Dec 13, 2011 9:33 am

Hello,
I am evaluating your software and I have some questions to ask:

The current version of our .NET application is distributed using the ClickOnce

I need to automatically uninstall this version during the instalation of the new version

Is this possible with InstallAware and which version I will need?

Thank you, Honza Filipsky

How would you otherwise uninstall a ClickOnce application?

There is an uninstall link in the Control Panel / Programs And Features
(this is the name in the Windows 7, there are some other names in older Windows versions)

I know I can run some DLL or EXE during the instalation, the question was whether there is
some plugin or script to simplify the transfer from the ClickOnce deployment to the new
deployment method (using InstallAware)

Thank you, Honza Filipsky

Hi,

Unfortunately, there isn't. You would have to read the registry for that value and manually invoke it using the Run Program command.

Looks like ClickOnce has both a QuietUninstallString and an UninstallString in the registry. Does anyone happen to know where I should run them? Should it happen in Process (Un)Installation?
