Removing install via registry

Hi folks,

One of my custom actions caused an error during the uninstall -so I am forced to remove my application via deleting its corresponding registry values. Before I begin, will deleting those registry values allow me to (Run/Uninstall) within Installshield? Currently, if I try to run or uninstall within Installshield I run into that error I mentioned earlier. Will installshield recognize that my application has been removed (via registry)? Thanks in advance!

Assuming you're talking about MSI: If a bad custom action is prevent the uninstallation from working, your best option might be to create a fixed-up build of the MSI and then re-cache the MSI on the target system by running:

msiexec.exe /i product.msi REINSTALLMODE=voums REINSTALL=ALL

After that, the uninstall should work fine.

(Deleting the registry information by hand is painstaking work, doesn't adjust shared-file reference counts, uninstall COM information, and so forth...)
