currently I have the problem to unpack an archive file which was packed as self extractor in 1998. I guess that this file was created with the operating system W...95. The associated file archiver was ARJ 2.55b ALPHA TESTWARE Copyright (c) 1990-96 ARJ Software. Jul 16 1996.
which works/has worked on DOS level. The core problem is apparently now that obviously the created self-extracting archive is not extractable across different operating systems, because the runtime environment is completely different today (e.g. 32-bit --> 64-bit, etc.). Presumably, the self-extracting archive can only be extracted under the operating system.
Unfortunately I don't have an old operating system to try this, nor the hardware used at the time of packing to run it.
I have now tried to solve my problem with the DOSBox 0.74-3 program. The existing ARJ.EXE packing program can apparently be started normally with it. However, the existing self-extracting archive does not. In DOSBox the following error message is issued: This program cannot be run in DOS mode.
Does anyone have an idea how to solve this problem?
