Hi,
I am trying to detect if another product is already installed before my product
installs and I want to only allow installation if the other product is present.
I believed this was quite simple but I have a problem.
I used an Upgrade table to detect for the other installed (based on its Upgrade
Code)
<Upgrade Id="{1D7F380B-A6A5-4CD1-86F3-F305B910C9C6">
<UpgradeVersion Minimum="0.0.0.0" Maximum="16.16.16.0" OnlyDetect="yes"
Property="PRODUCTINSTALLED"/>
</Upgrade>
And then I use a condition to prevent installation if the other install is not
present.
<Condition Message="A compatible host application must be installed to install
this Tool Pack">
PRODUCTINSTALLED <> ""
</Condition>
This works great during installation and blocks the install if the installer is
not present however when trying to uninstall the application the condition
always blocks. I believe this is because the Condition is processed during
uninstall but the upgrade is not and hence the PRODUCTINSTALLED is not set.
Am I going about this the right way? Or is using the <Upgrade> element not the
correct way.
Any pointers would be gratefully appreciated.
Many Thanks,
Kevin
