How to Stop Uninstall from Running?

[dennism]

Hi,

So if I do the following:

1) Build and deployed a web setup and then installed onto a number of PCs.
2) Rebuild the installer files and upload on to web server.
3) When a user reruns the setup program InstallAware wants to uninstall first, see attached.

How do I stop this and simply install over the top?

Second question, if the program is running it still seems to uninstall without a reboot - why?

Thanks for your help.

Dennis.

Hi,

This is part of
the installation script (old version removal). The reasons for the old
version removal are non-trivial, they cannot be worked around in Windows
Installer unless a patch is being applied; but the native engine is far more
forgiving and will not suffer from this limitation.

The removal of the previous version before installing the new one is a part of the setup script (inserted by the template you used).

You can turn on the native engine by setting the variable NATIVE_ENGINE to TRUE).

That may help - how do I do that?

Also, as part of the uninstall runs a post uninstall script - can this be stopped?

[giaviv]

What kind of program are you running?

Which post uninstall script are your referring to?

[dennism]

I'm usung InstallAware 12.

The post uninstall script is actually a VB.NET prpogram that does some database work after the uninstall is completed. So when they dust do a reinstall I do not want this program to run.

Hi,

What does this script do?

[dennism]

THe uninstall VB.NET prpogram does some database work on a backed SQL database after the uninstall is completed.

So when they user reinstalled, I do not want to run this program - this is why I asked if I can stop this selectively.

[giaviv]

Are you able to check in your script if the script has already ran?

[dennism]

Yes, but I want to stop it from running not check if it has BEEN run. If it runs, then it's too late.

[giaviv]

The easiest way would be to stop it form running within the script if it already ran - is that an option?

[dennism]

I understand what you are saying but I DO NOT WANT to run it that it its never been run on a reinstall.

[giaviv]

You can, in your MSIcode, check if MAINTENANCE is TRUE - if it is, that means that the setup has already been installed.

tThanks, this is what I'm after.
