certmgr.msc not exporting all of the selected certificates


hello-

i'm experiencing weird issue i'm hoping can shed light upon.
have need export of certificates located within "trusted root authorities" (localmachine\authroot) store, single file.
start certmgr.msc gui (as administrator), select store, "certificates", , see there 378 entries.
change 'focus' pane showing certificate list, , hit ctrl-a select "all" of them.  choose "export" task,
, save them .p7b file.
same issue happens if select first cert., scroll bottom of list , hold shift while selecting last cert ..instead of using ctrl-a.
straight-forward , looks works perfectly.

however, when process resulting .p7b file-  only 214 certs. exported.

when (winxp sp3) registry, under hkey_local_machine\software\microsoft\systemcertificates\authroot\certificates\
378 'keys' present.

i've experienced issue on both winxp sp3 system , win7 sp1.
i'm not sure if problem registry corruption (on both systems?!), certmgr.msc itself, or limitation of .p7b file format?

thanks in advance thoughts and/or insight this.

hi,

whether checked include certificates in certification path if possible ?

if exporting certificate pkcs #7 file, have option include certificates in certification path.

please try use other file format , check result.
