Need help in getting backup location in rollback custom action
I have IS 2019 Enterprise license. I have created a patch (.msp) over an existing .msi (prepared by my predecessor) file which replaces existing files while installing it and after uninstallation of the patch original files are restored to original location. But I am not able to find out backup location where the patch stores existing files while installing. I have .ism file of original .msi file and newly created .exe which is used as patch Can someone help me with how can I find out backup location ?
