[Running Windows 98 in 2020 and beyond...]

This is my "official" Win98 keyboard. 

[Is the floppy disk dead?]

I'm using floppy disk to memtest the RAM on the old Pentium MMX and Pentium II motherboards.

[Maybe long path issue with legacy software]

Thank you jaclaz,

I did further experiments and it seems that permissions are not related to this problem.

Then I moved the whole folder containing this installer to another PC running XP and it had exactly the same behavior: the short path does work, the long path doesn't.

Eventually I moved the same folder to another PC running Win98 and it had exactly the same behavior BUT with a verbose error message (photos in attachment).

You are right: the problem is not related to the OS but it is related to this installer. I think I don't need further investigation.  

 

[Maybe long path issue with legacy software]

I am migrating some legacy software (native for Win95, Win98, NT4.0 as AutoCAD 2000, Autolisp/ARX libraries, plot /CNC drivers) from an old XP computer to another computer running Win 7. This legacy software runs with no issue on Win 7 32bit with a few tricks (run as administrator, run in compatibility mode XP2) but, during installation, I've found a problem; I tried to run an executable from a long path but it didn't work:

C:\Users\cad2000\Desktop\ASUS_Q87M-E\Aggiornamenti_AutoCAD2000\risolve_stampa_autocad_2000\Plotupdate2000\Plotupdate2000>setup.exe
Impossibile eseguire il programma specificato.

Sorry for the italian language. I suppose it translates to: unable to execute the specified program or the system cannot execute the specified program.

But modern software runs from the same folder with no problem at all.

Then I moved the folder of the same legacy software to the desktop and the executable worked fine with no issue:

C:\Users\cad2000\Desktop\Plotupdate2000>setup.exe

The only difference I can see is the length of the path.

Do you think the legacy software can have problems with long path names?

 

[Hello from Italy]

Thank you.

[Hello from Italy]

Hello world,

I service old CNC machines still running DOS e WIN98.

My PC at office runs Win 11 but, at home, my personal PC runs MX Linux.

I am happy with all of these OS.
