[aprssig] Windows 7

The clue is in the name "UiView32"  :-)

Some info that may be of use to you (and others with Win7 PC's)

At work, we've recently "built" some device remote controlers based on 
small "NetBooks" (Compaq Mini's to be precise.)  That run Windows 7 "Home 
Starter" edition.

I found during initial experiments, that even old Win3x programs (16 bit) 
work well, and are able to use the Virtual COM Ports created by 
USB<>RS232 devices (Prolific chipset in this case, and you can also nail 
down said com ports, to always appear as the same COMx: each time, in 
exactly the same way you can in Win2k onwards.)

It is (even on Home Starter!) posible to run such app's in their own 
memory space, in a sort of Virtual Machine.  However, the PC's CPU gets a 
real good hammering doing that, that will affect battery run time.

I "tested" this, with some old 16 bit programs I wrote years back for 
work, to work as a controlers/indicators for some E-Field probes and 
other instruments we support.  They worked very well.

The recent device controler project resulted in a Windows 32 bit program, 
that works well, launched at system startup time too.

There is mention in many places, that the Home Starter Edition of Windows 
7, can only run up to three applications simultaniously.  Oddly, I did 
not find that, having (at one point) 5 apps all running together just 

I expect that UiView32 (and many other old Win16 and not so old Win32 
programs) can be made to work well on Win7 (32 bit versions) with a bit 
of patience and creative configuration.

I've been told and seen it documented however, that the 64 bit versions 
of Win7 do *NOT* have any 16 bit support.

I've not had such a PC to play with yet, but I sort of suspect that even 
in the XP Emulator VM they include, getting *Real Time* access to the 
outside world, might be an issue for some applications.

Run as a full Adminisrator when installing older programs, and you may 
need to set a flag in any shortcut, to "run as administrator" as well.

One caviate, that is quite well known now.   *DO NOT* install older non 
Win7 (or Vista) spec'd programs anywhere in the (often default) "Program 
File" structure.  The Windows UAC protects that from apps that write to 
that area, so any program that use .ini files for example, that exist (as 
they commonly do) in the app's own folder with the .exe, will fail to be 
altered, so it appears that you can't save changed settings etc.

I forget exactly where, but the settings are saved, but in a "diverted" 
place somewhere.

Using a unique folder well away from the "Program Files" structure to 
install the program in question, does not have that limitation.   MS 
would prefer us to use the Registry for program settings data, but that 
in turn is fraught with issues.  One false move and ...................

Of course, if the app's save their settings files in the place specified 
by the system variable %APPDATA% you don't get that problem, but then 
different users get different settings.  (Can be good, can be 

To see where that is on your PC, open a command line window, and enter 
the command:-

That works on Win2k and later just fine.   Many programs will also even 
let you use that system variable as part of a path in a setup dialog or 
.ini file setting.

Conclusion?  Windows 7 32 bit versions, should be OK for just about all 
"Ham" app's that work OK on Vista, and many that work on XP or earlier, 
right back to Windows 3x apps too in some cases!

Windows 7 64 bit versions?  Good question, well presented, unknown at 
this time.  Sir!
