How do I install MUI 3.8?

[2J4EZ]

Hello all I need help again

Ive managed to install os 3.9 on my new 4gb card,I now need to install mui to use ibrowse.
Every time i try to install it it comes up with a error about " ",line 299. (im using the unarch from 3.9 dock bar to unpack it)

Ive tried unpacking to ram disk and installing from there same error.
Been searching on the internet and some one suggested to use installer 4.3 so i downloaded it and have no clue how use it

Anyone no how i can get this installed?.

Im trying on a real amiga 1200 not a emulator

please help thanks for your time

In not home at the moment will be in about 1/2 hour I'll install boing bag 1 and 2 and let you no how I get on

Can't install boing bag 1 I need a CD ROM drive for my amiga
I put the os 3.9 CD in my mac and copied all files from cd to memory card and installed it that way.

I had cd rom drive  i used with IDEFIX97 but that was ages ago (about 7 years) so can't place it to hand .
anyway to mount a iso on a amiga? if i could iso my os 3.9 disk

Its downloaded im gonna install it and give it a go hope it works thanks for the replies so far

Ive downloaded it and installed it,the AmigaOS3.9.iso is located on my CF card

Ive gone into the shell and typed mountdiskimage  drive cf: AmigaOS3.9.iso and got device not found. maybe i did this wrong? should i copy this .iso file to my work partition and try again?

UNarc on a pc did that and it gave me the " " line 299 error
All i want to do is install mui and get ibrowse to work seems this system is very hard to use every time you install something its headache after headache (maybe it just me)

I'm a linux user and its lots easier than Amiga os

I followed a youtube video and downloaded a few files and put them on my CF card along with the Amigaos.3.9.iso then clicked start its suppose to mount the iso on my desktop but nothing shows up

Finally got Boing bag 1 installed via Winuae now boing bag 2 wont install it tells me its currpt im going to download it again

UPDATE..

I Started again I format both partitions and done a complete fresh install of os 3.9.
I previously installed 3.9 over 3.5 now my icons look better on a clean install.
However mui 3.6 still wont install on my amiga or the emulator same error.
I'm going to call it a night for today and try again tomorrow.

Thanks for all the help ive been given so far

MUI 3.8 is now installed.

For those having problems installing MUI3.8usr.lha unzip it with LHA, i typed:-

lha x MUI3.8.lha. I first placed it in the work folder unzipped it with LHA then ran the installer and it installed fine
