: are they still associated? When you doubleclick on the zip file, does it open in PA?
Well, most were associated. The ZIP extension though… maintained the association with the Windows default, meaning when I double-clicked upon a .zip file in Explorer, Explorer opened the file. I could have fixed that by going directly into the registry, but I fixed it instead by clicking upon Tools, Folders Options… then selecting the File Types tab, then scrolling down to the .ZIP extension, and clicking upon the Change button.
That’s corrected now, but I noticed that many of the File Types listed there do not expose the Delete button any longer when I highlight them. If you can duplicate the problem by deleting the extensions, and confirming the problem that would be helpful to me, and possibly to you, but if can’t duplicate the problem, then there must be something goofy going on with this particular machine and I’ll have to live with it until I figure out what’s going on.
: p.s. is there an reason for not rebooting your system, server or something?
Yes, it’s a server, and rebooting doesn’t fix things and it ends up as a waste of time as the boot time takes awhile.
I took a look at what was going on with Windows Registry API (using Rohitab’s API monitor) and noticed that after changing one of the items via the Change button under the Explorer File Types tab, Explorer then re-reads the keys that were changed.
The calls work as follows…
RegCreateKeyExW, “.01\OpenWithProgids”
RegSetValueExW, “PARAR”
RegOpenKeyExW, “.01\OpenWithProgids”
RegCreateKeyExW, hKey:0x80000001, “Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts.01\OpenWithList”
RegOpenKeyExW, hKey:0x80000000, “.01”
RegQueryValueExW…
There’s alot more going on but it appears that after the key gets set, it gets closed, then reopened, then requeried, and there’s a heck of alot of enumerating going on as well, but I believe it’s the fact that after the key is updated, it’s then re-queried.
I didn’t check what’s going on inside PowerArchiver, I figured you guys already know what’s up there. ;-)
