I'm writing a bit of code to determine if specific software is installed on a windows system. What I'm looking for is a specific key named "Version" under a hive: "SOFTWARE\\VENDOR\\PRODUCT" but I've found out that this product, when uninstalled, leaves the hive (I hope I'm using the right word here) there, but removes all keys from that hive. (E.g. the SOFTWARE\\VENDOR\\PRODUCT still exists with nothing underneath)... when I use getKeys to get a listing to pattern match for "Version", I get an error:
Can't call method "GetValues" on an undefined value at C:\scripts\reglist.ovpl line 19.
Is there a "exists" type function for the Win32::Registry perl module that I can use to test if the key "Version" exists before trying to open it?
Thanks;
Keith
