I'm administrator, and I'm not sure what properly registering is to you. For me it's double clicking on an unknown fileextention, and selecting the application to open it. I'll check if I have any software installed that might influence those registry values. Could you have a look at my registry backup and see if the entries for ASE file make any sense ?
I guess there are two way to manage fileassociations on my OS ... one is somekind of easy setup and the other is "Advanced" which allows me to specify the different operations for a certain file extenion in "Folder options->File types". I'll attach a screenshot. It's a german system though.
You seem to be right that my file associations are really broken. I just checked and did not see .ase file extention listed under "Folder options->File types". It opens fine thought. So I just clicked new fileexnteion and added "ase" ... which resulted in Windows showing the following information about ASE.
I then checked the ft2000 entry which should also be included in the backup, and it's empty even though the ASE files are opened with deepexploration.exe somehow. I'm puzzled.
Probably the problem isn't common enough to be fixed by CCleaner, guess I'll just clear all those "broken" extentions and reassign them by hand. I'll do it later though, I'm in no hurry if you want more information on this just tell me what you need.
Thx for the pointers.
PS: I feel kind of dumb now for not checking "File types" before.
EDIT:
ok, seems to be a bug in CCleaner... it also lists all my WinRAR associations too, and only those which are "Forwarded" to HKEY_CLASSES_ROOT\WinRAR.
For example if you install winrar it registers HKEY_CLASSES_ROOT\.r01 and put a "(Default) = WinRAR" into it. That's all it puts into it and my Windows Explorer knows what to do then.
