TI 11.tib files suddenly no longer associated

Vista Home sp2. Double-click on .tib files and nothing happens. They suddenly don't have the icon they used to have...have a blank default icon instead.
This happened prior to installation of Vista SP2.
Tried associating the files with Acronis True Image Monitor and that does nothing.
I did a reinstallation repair of TrueImage11.8053_s_en.exe and that did not fix the problem.
I used to be able to double-click on tib files and open them up to see the files within - can't do that anymore.
I can still mount and unmount within the Acronis software but that is not as convenient.
What has gone wrong?? Is it some Windows Vista update that did this?
Help...

 

Try this:
1. R-click on the .tib file and choose Open With
2. Select Choose Program then Browse
3. Navigate to the main TI executable file and select it.

 

Yeah, I know, I tried that. All that does is open up Acronis True Image the software...it does not just open the tib file immediately as previously so that I could "explore" the contents.
Thanks for trying to help.

 

Some of the regular posters here say that Ver 11 is very buggy ... even worse than the previous ver. 10. Maybe you're seeing one of its bugs.

 

Vista as the OS looks after file associations once they've been tagged.

Did this untagging happen after installing SP2?

Have the icons disappeared also?

It might also be a registry corruption which if so, the easiest thing to do would be to delete all references to TI in registry and then re-install TI.

 

@bodgy
I had this problem BEFORE installing Vista SP@ so I can't blame it. I'll try your great suggestion. I downloaded the latest Acronis 11 update so will install that after cleaning the registry.
Thanks.

EDIT: Totally removed Acronis 11; used the Acronis Clean Utility; used a reg cleaner and then installed the latest 11 update...still can't "explore" the tib files. Must be something I installed lately or a Windows update. Giving up on this.

 

Noticed that Acronis True Image Backup Archive Explorer in device manager is dated 2005. There's supposed to be a 2007 version of it. Where can I find it?
Completely uninstalled regcleaned and reinstalled TI 11 with latest version and still cannot "explore" the tib files. It looks like Acronis True Image Backup Archive Explorer might be what allows opening the tibs in Vista explorer

 

I hesitate to post here in that I don't have Vista but rather XP, SP3. Additionally I'm using TrueImage Home 2009 so the image I'm posting might not apply. Opening Windows Explorer and right clicking on a TIB file this what I see. The default for Open With is Windows Explorer.

 

Yeah, I know but associating Windows Explorer does nothing. The tib files used to have an odd Acronis icon on them...I see yours does not...and I could double-click on the tib file to see the contents in Windows Explorer.
Did I just dream that I could do that?

 

No you didn't dream it. It's working for me but of course I have no way to test it on Vista. Opening this displays the files.

 

Thanks, for confirming there IS such a feature.
