I'm looking to purchase a copy of Advanced Installer, but I can't seem to figure out what version I need. I have a program that installs many registry entries in the HKEY_CURRENT_USER. Upon installation, I need to check to see if the registry keys and values already exist. If they do not already exist, the MSI should create them. If they do already exist, I do not want to overwrite them.
I read a few posts on this forum, and I found a few posts that described a "never overwrite" feature. What version of Advanced Installer do I need (Pro, Enterprise, etc) to have access to this feature? Also, if there is a better way of handling this, please let me know.
Thanks in advance.
