RABCDasm

Im new to this, and i decompressed and everything and have my file ready, but whenever i go to "rabcasm client-1/client-1.main.asasm" it says

object.Exception@assembler.d(382):
client-1/client-1.main.asasm(???):
Unexpected end of file

0x00452484
0x0042BEA8
0x74568494 in BaseThreadInitThunk
0x77CC41C8 in RtlAreBitsSet
0x77CC4198 in RtlAreBitsSet

and i did rabcasm client-1 by itself and it said

object.Exception@common.d(81): Failed to open file "client-1": Access is denied.

0x0042BEA8
0x74568494 in BaseThreadInitThunk

How do i fix this, i cant find anything about this and im on cmd with the correct file path and i opened it with admin.

If you are doing everything right, try compiling RABCDAsm from source on your computer. The only result I found of a similar problem said that that was the fix. Otherwise, make sure you are following the instructions exactly. Starting with a .swf file that isn't lzma compressed, unless you have support for that, run:
abcexport example.swf
rabcdasm example-0.abc
[make changes to the .asasm files in the example-0 folder]
rabcasm example-0/example-0.main.asasm
abcreplace example.swf 0 example-0/example-0.main.abc

It's not the end of the world if you don't get it working. JPEXS does everything RABCDAsm does, just with slightly worse workflow in my opinion. If your project is complex enough that JPEXS feels clunky, you should be editing a source anyways.
