[RESOLVED] General question about packages

Hello,
I discovered the WAPT solution some time ago and I'm planning to do a proof of concept (POC).
I haven't found the answer (perhaps I haven't searched properly...).
I'd like to know if WAPT packages automatically replace software installed on a PC.
For example, if Firefox is installed on a PC, will the package pushed by WAPT uninstall the previously installed version of Firefox?
Thank you for your answers!

Hello,
it all depends on how you configure your package.
If you use the `install exe if needed` option with the `min version` parameter, it will only install if the already installed version is older.

After a few tests, I confess I don't understand how min_version works
For example, I installed Firefox 76.0, then created a package with an older version 71 like this:
Code: Select all
install_exe_if_needed("Firefox Setup 71.0.exe",'-ms',key='Mozilla Firefox 71.0 (x64 fr)',min_version='71.0')
or that
Code: Select all
install_exe_if_needed("Firefox Setup 71.0.exe",'-ms',key='Mozilla Firefox 71.0 (x64 fr)',min_version='71.0')
The package is reinstalling itself over version 76 when it shouldn't.
Did I miss something?

In your situation, WAPT worked as expected: you requested to install version 71 as a replacement for version 76.
install_exe_if_needed will install a newer version of your software if the version on your machine is older.
If the version on your machine is the same as the package version, then the package will only report to the server that your software is up to date without installing it, because the operation will have been rendered unnecessary.

In my test, I already have version 76 installed.
The version of the WAPT package being
71 It's older and shouldn't be installed?
Or do we need to proceed differently so that it doesn't install an older version over a newer one?

Thanks for the replies.
So it seems possible

For Firefox, it's a bit different.
The Firefox uninstall key contains the Firefox version number.
So if the software's uninstall key isn't present, then the installation is restarted!

Okay, noted.
Here's how I get around this, for example, with version 76 already installed
Code: Select all
softname ='Mozilla Firefox'
listFF=installed_softwares(softname)
#print(listFF[0]['version'])
versionInstalled=listFF[0]['version']
versionPackage='71.0'
if versionInstalled >= versionPackage:
print('version installée supérieur a celle du package')
else:
install_exe_if_needed("Firefox Setup 71.0.exe",'-ms',key='',min_version='71.0')

Absolutely, but the uninstallkey is still necessary

Is this necessary for WAPT to consider that the software has been installed correctly?
Or just advice on how to uninstall via WAPT if needed?
