Hi,
We are aware of this issue, and we hope to solve it soon. Until then here are some workaround:
1. Delete those values from the "Registry" page, rename the empty key and them add them back manually.
2. You can install your package, and export the registry entries to a .reg file with regedit. After this delete those values from AI, rename the empty key and import the saved .reg file.
Regards,
Gigi
