Uelr

[ADMIRAL]

Hello friends
I've seen Uelr in compression methods several times
But I didn't see it in any compression.
Until I found it in Masked_Compression_v3.0, but according to this Method
uelr+srep+lolz:dt1:dtp1:dto1:dtm1:dtw1:dtd1:mtt1:m t4:d100m:tt1h14:fba4096:mc1023:bc8:blr8:bmfbt4:d15 8m:fb273:mc1000000000:lc8 does not work and shows Uelr error at begin every time in every compressor.
ٌWho can help me by show the way.

This is Uelr Settings in arc.ini

[External compressor:uelr]
header = 0
packcmd = uelr uv $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

Even tested by changing uv to ulx
