I check the MD5 and are the same as you said.
MD5 b5f856d86a5839fa62ee45401a345697 * Universal_Extractor_1.6.1.58_sl2p_111215_13-29.7z
MD5 04ca4bfdb2f98af2a88bddfa5ffb5409 * UExtract.exe

yes I disabled the antivirus (Eset) before but the problem persists.

I try UnEx in two machines:

Windows Xp sp3 NetFramework 4.0 (32 bits)
system language: spanish

and I ran the UniExtract in windows vista sp2 NetFramework 3.5 (32 bits)
system language: english

how I see the ID language?
sorry but I don't know the availability of MUI in the system and its language

in windows vista I had never installed UniExtract this is the first time I try to install
in windows xp I clear the registry with several programs (Ccleaner, WinTools, ASO)

the previous version (1.6.1.Build.57) of the program worked well in XP did not have any problem but,

the latest version (1.6.1.Build.58) when I run the installer shows me the error stated above (in the image).
the program did not show any other error only that I showed in the picture.
