I seem to recall that in XP prof 64 there was a problem with xp only supporting ID3v1 tags wheras most taggers used ID3v2 I'm just wondering if this is still the case. as I use 32 bit vista can't check this out.you may want to check what your tagger is using
Ok looks as if the reg clean removed a registry entry for a dll that is needed to edit tags. Check in event viewer for the error message and it should mention the .DLL in the details you then have to re-register that dll
in an admin cmd prompt regsvr32 [dll name].dll and see if that helps.
The only error message 0x80040154 found in event viewer is 1 year old, and do not seem to be the cause of my problem It is very old, I didn't have any problem at this moment
I think that this problem does relate to either an unregistered DLL or windows API, caused by the reg cleaner without the name though I dont think there are many options.
apparently 32bit and 64 bit use different calls so you could try the 32 bit explorer
alternatively other than a re-install it may be an idea to look at a third party solution one Here is old but may work. suggest you have a look for modern alternative . I would keep checking error log to see if the error message appears and then try to re-register the missing call.
if I do come accross anything I will post here
good luck! think you may need it as there does not seem to be any info on this fault that i can find.
Just one thought are you running SP1, iinstalling / re-installing this may sove it though i don't hold out much hope. other that that try an "sfc /VERIFYONLY" see if that reports anything.
any way sorry couldn't help and good luck with re-install
Edit 2: Ah! I've found the solution! I downloaded shmedia.dll (that is from Windows XP) and typed regsvr32 shmedia.dll, MP3 tags are back!! But I still have the problem with de thumbnails with my video files (and properties are still not shown)
