I have created two custom actions that does the following jobs:
1. Create a file based on the property passed to the installer. eg
msiexec /i installer.msi /l*v out.txt IPADDRESS="192.168.2.2.08"
The custom action will create a file that will contain the data as:
{
"ip":"192.168.2.208"
}
2. Another Custom action will remove the residual files that the executable
created during uninstall.
Now, I have called these two Custom Action in my Wix file as:
<CustomAction Id="WRITEFILETODISK" Execute="immediate" BinaryKey="SetupCA"
DllEntry="WriteFileToDisk" />
<CustomAction Id="ResidueRemove" Execute="immediate" BinaryKey="SetupCA"
DllEntry="DeleteResidue" />
<InstallExecuteSequence>
<Custom Action="WRITEFILETODISK" Before="InstallFinalize">NOT
Installed</Custom>
<Custom Action="ResidueRemove"
After="InstallFinalize">Installed</Custom>
</InstallExecuteSequence>
The problem I am facing is that, when the user again tries to execute the
command given at number 1, it will call ResidueRemove. I want to prevent
this scenario. One solution could be calling the ResidueRemove during only
true uninstallation. If this method is ok, how can I implement it. Another
Solution could be prompting user that the product is already installed. If
so, How can I show prompt to user that it is already installed?
Thanks.
