SOLVED by ME !!!

Reason: during instalation JAR process was interapted by anything
(restart, lost power, lost connection, etc.) Result of it is bad REG
creation !!!

Look into "C:\System\Install\Registry\" .. U will find files like
"*.reg" (ex. "1013EF8D.reg").

Normal file must be content next (example of "100FF7C1.reg"):
°C:\private\102033E6\MIDlets\[100ff7c1]\ uids @appUid:270479035?? C
HWarDiaryBurma
[NP] Rovio °· ·· -· = )
c:\private\102033e6\midlets\[100ff7c1]\1149154 895_war_diary_burma.jar
µ " ".
µ J 4WarDiaryBurma

And, corrupted file look like:
? ,??t¦??? ??? e,(?-P? ?pl?R)‹??3?€?T?›?
??"M% ?? D
†I¶3?!r?j:??k??/?™:Z?????#?€-m?? ‡??...‹?J›f

.... or sth else (means not logical organization as first)!!!

Symbian is smart a little ... before U try install new JAR App, it
rescan system for REG, then it try to read corrupted file, it just stop
a process of installation with primitive error "Unable to Install" !!!
Also if u look in App.Manager .. not all installed JAR are shown !!!

Solution is: JUST DELETE THIS CORRUPTED FILE !!!
