Yes

Summary

How to uninstall a setup.exe silently which contains Multi-Instances

Synopsis

When attempting to silently uninstall a setup.exe which contain Multiple-Instances you may find that the uninstall fails using the normal approach of: setup.exe /s /v/qn

Discussion

When uninstalling a setup.exe via the command line which contains multi instance it is necessary to state which instance is being targeted.

This is done by using the /instance= switch

For example:

/instance=1 This will target instance 1 of the installation
/instance=default This will identify the instance that is installed by the base installation package

An example command line to uninstall a setup.exe silently which contains multiple instances could be:

Setup.exe /s /instance=default /x /v/"qn"
