Subject [jira] Commented: (DAEMON-131) Win64 build: //DS// fails to delete registry keys
Date Fri, 11 Dec 2009 07:23:18 GMT


Mladen Turk commented on DAEMON-131:

Thanks for the patch. I'll apply it but slightly modified because KREG_WOW6432 is not present
for all compilers, so additional #ifdef will be required

happen on ia64.

> When creating and accessing the configuration registry keys, the tool uses CreateRegKeyEx
with the KEY_WOW64_32KEY flag, telling windows "Use the 32-bit hive instead of the 64-bit
one".  Maybe this was done so that 64-bit daemons could use the configuration from 32-bit
> Anyway when it's time to go and delete the configuration from the registry it uses the
ancient SHDeleteKey call, which tries to delete the key from the 64-bit hive, which fails,
so the key is left behind.
